3 ton gas steam boiler thailand

First, when the flue temperature dropped to below 50 ℃ Solution: Check the tail may enter the flue if heated, while the flue thoroughly remove soot. No burning flue tail, can be re-started ignition; if burning, should be replaced, repaired burning member. Second, the combustion chamber when the negative pressure is too large Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1 hour and stable, open the inspection hole inspection; after inspection after confirming the fire source, before start the fan ventilation. Third, shutdown or fire, air gun valve ajar solutions: reinforcing and electric 3 ton steam boiler thailand feed water drainage, or open the valve economizer recirculation tube to protect the economizer is not burning. Fourth, Kai, during shutdown lower furnace temperature, a solution of unburned fuel in the furnace: extinguishing device immediately put into vapor, carbon dioxide or other devices off fire. Five burning improperly adjusted, with insufficient wind or with the wind unreasonable Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan. These are the methods of electric heating steam boiler fast boiler to provide you with the handling of soot in the chimney, if you use electric steam boilers, with more than five can control their own boiler equipment need to be cleared up the flue, and select the appropriate method .

What is the main danger 3 ton steam boiler thailand? The main danger emergency steam boiler 1, surveillance, hazard control boiler steam boiler regular inspection tours, and monitor pressure, water level, temperature and combustion conditions to control the boiler operating conditions. And to take timely measures to ensure safety. 2, the processing operation of the steam boiler in special circumstances: (1) water shortage phenomenon: When the boiler water, the water level below the water table level limits not visible, low water level alarm emits an alarm, bell lights, low interlocking means so that the water level blower, fan, etc. closure operation; boiler exhaust gas temperature rise, a serious lack of water, lake taste top coke production, the door can be seen from the red-hot waterwall tubes, tube deformation or even explosion pipe, can be heard blasting sound, smoke and steam discharged from the door to see the fire door. Treatment: When judged as a serious water shortage, should an emergency shutdown, non-serious water shortage boiler water to the boiler. Immediately stopping the supply of fuel, the wind stops blowing weakened, the front portion of the coal grate furnace Pa, the maximum switch the grate, combustion slag hopper falls quickly, with irrigated off, after extinguishing the fire, stop the wind, open ash door, the door to promote accelerated cooling. Note: Do not feed water to the boiler, shall take measures to prompt blood pressure, prevent the accident, to refrain from watering methods to the furnace fire put out the fire. (2) boiler overpressure phenomenon: a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line", the safety valve, the pressure is still elevated, issued overpressure alarm, steam temperature and steam flow rises cut back. Processing: weakened rapidly burning, manually open the vent valve or safety valve, to increase the water supply, sewage increase (normal water level at this time to keep the boiler), thus reducing the temperature of the boiler water a boiler drum pressure decrease. (3) boiler tube phenomenon: the waterwall tubes blasting significant audible pops or jet sound, until the furnace by the combustion pressure becomes the negative pressure combustion, flue gas and steam and has viewed from the fire door, the door does not close, etc. discharge, although the water supply amount is increased, but difficult to maintain the normal water level and the pressure reduced, the amount of water to abnormally greater than the amount of steam, the exhaust gas temperature decreases, the chimney white smoke, the furnace temperature is reduced, or even extinguished, water flow out of the bottom of the boiler. Treatment: furnace tube rupture is not serious and can maintain the water level when the accident not to expand, may reduce short-term load operation, serious burst pipe and the water level can not be maintained, must be an emergency shutdown. But the wind should not stop, should continue to Sheung Shui, lower wall temperature. Such as: lack of water wall overheating, while burst pipes, emergency shutdown should be prohibited to the boiler feed water, the withdrawal of the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of superheating boiler. (4) steam boilers will produce full of water, such as priming scene of the accident, should take timely and effective measures to eliminate given. (5) boiler operation, in the event when one of the following circumstances, should immediately shutdown :( a) boiler water level below the lowest water level gauge visible edge; (b) increasing water supply and other measures, but the water level continued to decline; (iii ) boiler water level exceeds the highest visible level, the drainage can not see the water level; (iv) to pump all the water system failure or malfunction, not bottled water to the boiler; (e) all of the water table or valve failure; (vi) is set in a stripping all space gauge failure; (vii) damage the boiler element and endanger the safety of operating personnel.

What are the overall structure of the boiler boiler structure includes two major boiler and auxiliary equipment. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, to avoid the boiler water containing a high concentration of salt and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In order to improve the design and performance assessment, often have to go through boiler thermal balance test. Direct methods to calculate the thermal efficiency of the boiler is called n-efficient use of energy balance, the heat loss from a variety of methods to counter the counter balance called computational efficiency. When considering the practical benefits of the boiler room, boiler thermal efficiency not only look, but also taking into account the energy consumed by the auxiliary boiler. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Dust contained in the boiler flue gas (including carbon black and ash), sulfur and nitrogen oxides are air pollutants, which can achieve emissions targets environmental regulations when unpurified indicators several to several tens of times. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Flue gas dust removal force used gravity, centrifugal force, inertial force and acoustic adhesion, static electricity and the like. Is generally used for separating coarse particles gravity settling and inertial force, centrifugal separation is often used dust bag filters and electrostatic precipitators having a high dust removal efficiency at higher capacity. Wet venturi - water film adhering water film droplet precipitator ash, high collection efficiency can absorb gaseous pollutants. Since the 1950s, people strive to develop the comprehensive utilization of ash, harm into. The manufacturing cement, bricks and building materials such as concrete aggregate ash. Since the 1970s and from the fly ash cenospheres extracted as a fire-resistant insulation and other materials. Future development will further improve boiler thermal efficiency of boilers and power plants; reduce equipment cost per unit of power boilers and power plants; enhance operational flexibility and level of automation of the boiler unit; develop more varieties to suit different boiler fuel; and improve boiler unit the reliability of operation of the auxiliary equipment; reduce environmental pollution.
