Measures to improve the thermal efficiency of the fuel gas-fired generating steam using in boiler wns type of chemical oil-fired boiler which is incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass steam boiler, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.
Gas furnace gas steam mass identification of the method for determining the gas quality of a gas steam oven, it must have a manufacturing license manufacturer, the manufacturer must have a manufacturing license, the users must purchase gas steam generating steam using in boiler with production of qualified manufacturers product. See calculation but also the strength and structural design aspects of the gas furnace gas and steam, the furnace is all vapor pressure, and steam oven gas liquid gas into the furnace pressure injection and suction two unpressurized species. Heat Transfer Fluid pressure element whether or not the furnace, it should be calculated according to the current standard boiler intensity calculated geotextile design pressure applied to the working pressure 0.3MPa, and not less than 0.59MPa. Secondly, it is necessary for the steam furnace gas pressure test gas, which when assembled in the manufacturing unit and the unit is mounted in use, a pressure test were performed after repair. Electrically heated gas steam boiler, its pressure test into pressure test, hydraulic pressure test and tightness test. Whether gas furnace electric heating gas or liquid steam boiler furnace, the manufacturing units have to conduct hydrostatic testing, hydraulic test only in the use of the unit, and should not pressure test. For electrically heated gas steam boiler furnace gas, but also in the manufacture of air tightness test unit and used to check the seal of the non-welded joints. Test Method airtight electrically heated gas steam boiler and the requirements of the relevant provisions of the pressure vessel is. For electric heating liquid gas steam boiler furnace, not required tightness test. At the same time, more stringent control of electric welding quality heating gas steam boiler, organic heat carrier due to the electric heating gas steam boiler easy to leakage, flammable, so the electric welding organic heat carrier furnace gas heating boiler steam requirements compared to a medium boiler water is high, the quality of welding should be strictly controlled electrically heated gas steam boiler.
Condensing a portion of the air preheater and use of double combination economizer design. Internal economizer heat exchanger elements using the new technology - the wings of the tube instead of finned tubes, a five-fold increase in heat transfer area at the same volume, latent heat of vaporization of the portion of the flue gas is sufficiently absorbed, effective utilization of the fuel energy, energy saving at the same time enhance the efficiency of the use of the generating steam using in boiler. Air preheater is further absorbed by the air and the flue gas convection heat latent heat of flue gas, and the air heated by the air preheater is connected directly into the burner tube, providing warm air for the fuel, thus improving combustion efficiency. This exhibition brings Chinese fast "Euromonitor" series boilers attracted a large number of customers, to give customers unlimited. Here, fast Boiler staff wish the exhibition every success.
Commissioning of Boiler gas generating steam using in boiler commissioning must be carried out after the hydrostatic test. Before commissioning, should be a comprehensive inspection of each furnace parts, electronic control devices, wiring, etc. are normal, water supply, oil furnace if opened, electrical contacts are in the set position. 1, depending on the size of the fuel consumption, the initial damper, the hydraulic pressure. 2, the power is turned on, the power switch to open the cabinet, the water pump starts furnace, (if the pump is rotated into the anhydrous, pump purge valve is opened, the air exhaust pump). 3, control checks whether the normal water level electrode. 4, check the burner operation is normal. Starter burner starts combustion when the water level rose to a predetermined level, the start of combustion is normal to observe: Start no vibration noise, stable combustion, no smoke, orange yellow flame, burning bright clear. Otherwise, to make the appropriate adjustment (refer to burner instructions). Note: The oil pressure between 0.8 ~ 1.0Mpa, after a good tune, do not easily change, oil pressure is too high or too low have an effect on burner performance life. 5, check the pressure gauge pointer swing is smooth, with or without loosening stuck. 6, whether the discharge check valve is set at the set pressure steam: Pressure controller first maximum working pressure, a safety valve is adjusted to the set pressure higher than 0.05MPa, when the furnace pressure was raised to whether the exhaust pressure setting, if exhaust , pulling the safety valve a few times, and try again, if not enough to deal with safety valve to adjust. Pressure relief valve setting: boiler rated pressure + 0.03MPa. 7, check the electrical contacts of the operation: When the pressure is raised to the maximum working pressure (not exceed the rated working pressure), should stop burning, open the safety valve blowing off steam, the pressure to a minimum operating pressure (maximum operating pressure is generally lowest set to 0.10MPa), combustion burner should be restarted. Note: When the adjustment screw should slow, especially when the pointer approaches the end, otherwise, damage the screw off the wire.
