Display complete: circulating pump, the operation of the burner, the boiler water temperature, water level, the current time, alarm records, ranging boiler operating state; easy setup: the boiler power, the operator can freely enter key 6 when operating parameters for the standby state (set) into the operating state (power on), the state out of operation (stop), the random standby state is set; functional: arbitrarily set the current time, alarm temperature, the maximum temperature of water, The lower limit of water temperature, the temperature of the circulation pump is turned on, the circulation pump shutdown temperature, the boiler switch time (divided into four time periods) and other operating parameters. The operator usually just press the start key to boot, press the stop button to stop, very simple. Second, the combustion system: imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) to automatically adjust the proportion of oil wind, good atomization, combustion, energy saving, It has flameout protection device to ensure safe combustion. Under normal circumstances, the combustor output temperature of the boiler with the combustion flame length is automatically adjusted, the outlet temperature of the boiler reaches the set value, the burner combustion is automatically stopped, when the temperature is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically. Third, the boiler: boiler structure according to the design pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination aesthetic form . Vertical CLHS mounted boiler combustion at the burner, the fuel is combusted within a slight positive pressure furnace, the flue gas temperature in the furnace radiation heat transfer, convective heat transfer and then enter the pyrotechnics, smoke box is discharged through the last. Smoke tube baffle is inserted, the smoke evacuation slow speed, heat strengthening, fuel combustion furnace to ensure the greatest degree of heat generated water, greatly improve the thermal efficiency of the boiler; CWNS horizontal boiler with full wet back three return structure, the flue gas flow length, reduced exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively prevent the metal due to thermal expansion and contraction result in reduced equipment life; large-diameter cigarette tube and macropores bridge the gap, the boiler at equal time scale coating thin and easy to clean. Fourth, multiple protection: boiler has multiple security: the drain leakage protection that is automatically cut off power; i.e. overheat protection boiler water temperature reaches ultrahigh temperature alarm, automatic stop and alarm the burner; i.e., protection of the secondary superheater boiler housing temperature exceeds 105 ℃ when, automatically cut off the secondary circuit, the boiler stopped working; anti-dry protection water level electrode bar that is well-real-time monitoring water level, for other reasons boiler water level reached below the water level is very low, the boiler stops working, to prevent the occurrence of dangerous dry. Five: Packing Insulation: white color board packaging, nice, closed Haonai corrosion, mechatronics, small footprint, and easy to use. Glass wool insulation for whole body type, light weight, good thermal insulation effect, and less heat loss.

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

Coal-fired steam boiler scale can cause harm and failure scale is the first coal-fired steam boilers, coal-fired steam boiler is the main cause of the accident, the danger main problems: wasting a lot of fuel: Because the thermal conductivity of the scale of only a few steel one tenth, so that the heating surface when the fouling of heat transfer will hindered, in order to maintain a coal-fired steam output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent fired steam cleaning, expose the metal tube so that the device primaries, and to reduce biological fouling of algae because silt impact. While the peeling effect of iron on the iron oxide and ethylene, prolong the service life of coal-fired steam boilers, to reduce energy consumption and improve productivity. Fired steam after a long run, the inevitable emergence of scale, the problem of corrosion, scale coal-fired steam boiler formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation, the coal-fired steam furnace with a series of physical, chemical, and finally heating surface to form a hard, dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, leads to a reduction endothermic coal-fired steam boiler waterwall furnace, burning coal steam boiler furnace exit temperature increases, the increase in the loss of coal-fired steam boilers. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of coal-fired steam boilers.
