To enhance the thermal efficiency gas boilers What environmental policy: the combustion efficiency of combustion represents the degree of complete combustion. To improve the combustion efficiency of gas boilers and environmental protection, we must try to adjust the combustion conditions and better organization of the furnace, fuel combustion, reducing q3 and q4. Gas boiler environmental protection reduce exhaust gas temperature: at present China's industrial boiler flue gas temperature is high, is one of the main reasons of the low gas boiler thermal efficiency and environmental protection. Each small boiler flue gas temperature decreased 15-20 ° C, 15 ° C decreased every large boiler, a 1% increase in the thermal efficiency of the boiler gas. Accordingly, to try to reduce exhaust gas temperature flue gas heat recovery, reducing heat losses q2, the fuel savings. Softened water supply and condensate recovery: boiler feed water softening treatment and condensate recovery measures is to improve the thermal efficiency of the boiler. Raw water contains various impurities and fouling material, if not the water treatment boiler fouling. Low thermal conductivity of the scale, so that once the heating surface fouling due to increased thermal resistance, gas boiler output decreased to increase coal consumption, reducing the thermal efficiency of the boiler. Boiler keeps running at rated load: When natural gas boiler overload, due to the amount of fuel to be increased, the coal seam thickened, grate speed, air volume must be increased to meet the increased load required. Thick coal seam and grate faster incomplete combustion of the solid increase in losses due to increased air volume, the short residence time in the furnace flue gas, some burning of combustible gas has not finished on the drain with the flue gas, so incomplete combustion gas heat loss is increased. Meanwhile, when the overload operation, since the furnace temperature is increased thickening seam, exhaust gas temperature increase accordingly, so that heat loss is increased. Boiler low load operation, the amount of reducing gas, the furnace temperature is lowered, deterioration of the combustion conditions, incomplete combustion loss q3, q4 is also increased. When the boiler load is only 50%, due to a significant reduction in temperature in the furnace, it is difficult to maintain stable combustion furnace. Low load operation relatively increased heat loss, the overload or low-load operation the boiler will result in reduced thermal efficiency of the boiler. Strengthen the insulation, sealing, anti-leakage, anti-risk: Due to the wall gas boiler, soda temperature heat pipe system is better than the boiler room air temperature is high, so that part of the heat pipe system and soda furnace wall to radiation and convection to the loss of ambient air, heat radiation loss becomes the boiler. Only the furnace heat of the heat loss, reduces the temperature of the furnace at the same time, it affects the combustion. Therefore, the use of advanced insulation materials to strengthen the walls and heat insulation boiler pipes, reducing heat loss and improve the thermal efficiency of gas boilers and environmental protection. Temperature and security issues to resolve gas steam boiler
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.
