Low NOx emission combustion boiler technology a boiler combustion boiler hypoxic hypoxia NOX emissions from combustion is the easiest way to control. And a combustion burner system does not need to make any changes, only control air flow into the furnace in operation, pulverized coal combustion process as close to the theoretical combustion air amount. Low oxygen combustion scheme can reduce NOX emissions by 20% to 30%. The program practical application subject to conditions. Low oxygen furnace, will increase the amount of unburned carbon, and more difficult for the flame of burning coal more obvious; Further, the CO concentration is also increased so that smoke, which will cause decreased boiler efficiency. Another problem is that for certain boilers, hypoxia causes the main combustion steam or reheat steam temperature is low. The burning coal to immediately, boiler efficiency and reduce the magnitude of steam temperature and other properties to determine the appropriate control value of flue gas oxygen furnace outlet (at or economizer) the specific embodiments. Second, air staged combustion technique combustion air into a plurality of strands, it is gradually mixed and pulverized coal combustion, so you can see the local area to reduce the air-fuel ratio, and the thermal decomposition of coal in the ignition phase, due to hypoxia, and thus the nitrogen oxide generation is suppressed. Air classification may be implemented within the combustor, the boiler can be completed within. 85% of the amount of air required for complete combustion is introduced to the main burner, the main burner combustion zone is insufficient oxygen for the fuel-rich conditions. Due to insufficient amount of oxygen, the flame temperature is low, the amount of nitrogen oxides to less generation of fuel nitrogen intermediates (e.g., NCH, NH3, etc.) will therefore not be oxidized NOX. Meanwhile, it has been possible to further reducing NOX generated in a reducing atmosphere to molecular nitrogen (N2 of), as a result reduces NOX emissions. An upper portion of the top floor is provided Ge overfire air (of OFA) spout into the furnace through which about 15% of the rest of the air, to avoid the high temperature flame zone, it is also possible to burn unburned carbon particles, to complete the combustion process.

Corner tube industrial manufacturers 4t steam boiler jordan is one type of chain grate steam boiler. ZG manufactured corner tube biomass fired steam boiler’s power is among 6 to 15 MW. This biomass fired steam boiler adopts corner tube pattern, self-supporting structure. The furnace and the descending fuel gas duct adopts total welding membrane water cool tubes wall structure, which has benefits of good sealing, lower heat reducing. Both air pre-heater and economizer adopt case pattern structure which is convenient to transport and install. As a top steam boiler manufacturer in China, our single drum corner tube biomass fired steam boiler made in China is both eco-friendly and high efficiency.

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.

In recent years, the state environmental protection is all the more attention we as a company with the times, in order to respond positively to the implementation of the national environmental protection requirements from coal to gas project. But the choice of boiler suppliers in this area quite a headache, after repeated comparison and investigation, we chose to partner with fast boiler. Fang did not disappoint quickly proved that the recommended boiler operation after use to fully meet our needs, both energy saving and environmental protection, high thermal efficiency, to a certain extent, cost savings for our fuel. --customer feedback
