10 bar town gas fired boiler steam pressure

When the weather gets colder and colder, people will choose different ways of heating, one of which is more convenient is the fuel-fired 10 bar town fired boiler steam pressure, but many people do not understand his use, so take a look at the following. Classified oil-fired boiler is a kind of boiler with many kinds of oil such as diesel oil, waste oil and so on. Its general structure and arrangement are similar to coal-fired boiler, and the common classification is mechanical type and steam materialized type. The characteristics of the bottom of the oil-fired boiler are to make the bottom of the furnace inclined to the back wall, which is the bottom of the heat preservation furnace, in order to obtain good combustion characteristics. This kind of boiler, for those who don't have a natural gas pipeline, Hope the boiler can run normally low cost, then the fuel-fired boiler is a very good choice. The fuel-fired boiler is an important symbol of the progress of the times, in order to serve the human being well and further perfect according to the needs of the people. Oil-fired boiler is designed in accordance with certain commercial standards, to a certain extent to ensure the excellent boiler, but also to a certain extent to improve the heat absorption strength of the boiler, then how should we use it? Design problems according to the oil-fired boiler inside the design of the boiler inner tank is larger, can store steam will be corresponding to more, suitable load capacity will become stronger, can be To meet the needs of different users, the cleaning of internal gall is also more convenient. The fuel-fired boiler with fire tube structure adopts the structure of triple-reflux fire tube, and the flame burns in the combustion chamber with high thermal efficiency, energy saving and consumption reduction, so it is economical and convenient to use. According to the unique design of the boiler, the use of the oil-fired boiler needs to find a set of operation steps suitable for the boiler and give full play to its function.

The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam 10 bar town fired boiler steam pressure to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).

The steam 10 bar town fired boiler steam pressure can be divided into three kinds according to the fuel (electricity, oil, gas), such as electric steam boiler, oil steam boiler, gas steam boiler, etc. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small steam boilers are single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. If according to the classification criteria above, there are a lot of steam boilers, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Steam The combustion part of a steam boiler consists of a chain grate and a drive device, together with a combustion chamber composed of a boiler rack on the grate frame. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters. This steam boiler has great resistance and needs forced blast. The cinder of a steam boiler, discharged from the back of the grate through Eagle's mouth iron and sent out of the furnace by a slag extractor. Steam boiler flue gas from the back of the boiler, by the steam boiler drum one-way smoke pipe forward, from the two-way smoke pipe back to the rear, then into the dust collector to separate ash, and then through the induced fan from the chimney exhaust Out. The above is the working principle of steam boiler, of course, the operation of steam boiler without other equipment, such as the induced fan not only undertake the task of exhaust flue gas, but also the steam boiler negative pressure operation necessary. There are also pressure vessels, thermometers, safety valves, pressure gauges, pumps, steam pumps, etc. All are essential for steam boiler work. Pump leak problem. The actual output flow rate of gear pump is smaller than that of theoretical flow due to the leakage of gear pump in the process of operation. The main leakage channel of gear pump is through the gap between the two sides of gear and the cover plate on both sides of the gear, which is 75% / 85% of the total leakage of the pump. Radial clearance leakage between gear top circle and inner hole of pump; clearance leakage through gear meshing. Because of the leakage of gear pump, the output pressure does not go, which affects the range of use of gear pump. In order to solve the problem of low output pressure of gear pump, the way of adding floating sleeve or elastic baffle on both sides of gear pump is adopted to reduce the leakage of gear pump and improve the output pressure of gear pump. Radial force imbalance problem. In the working process of the gear pump, the pressure on the outer circle of the gear is not equal, which results in the radial unbalance force at the shaft and bearing of the gear. This radial imbalance will accelerate the wear and tear of the bearing, reducing the bearing The service life also may cause the gear shaft to deform, causes the tooth top and the pump body inner hole friction, damages the pump body, causes the pump not to work normally. The common solution is as follows: (4) opening pressure balance slot on pump, leading high pressure oil to low pressure area, but it will increase pump leakage and affect pump volume efficiency; (2) reducing the size of the pressure chamber, reducing the pressure area acting on the gear teeth, and thus reducing the radial unbalanced force.

What is the main danger steam 10 bar town fired boiler steam pressure? 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.
