different types top gas fired water boilers

First, when the flue temperature dropped to below 50 ℃ Solution: Check the tail may enter the flue if heated, while the flue thoroughly remove soot. No burning flue tail, can be re-started ignition; if burning, should be replaced, repaired burning member. Second, the combustion chamber when the negative pressure is too large Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1 hour and stable, open the inspection hole inspection; after inspection after confirming the fire source, before start the fan ventilation. Third, shutdown or fire, air gun valve ajar solutions: reinforcing and electric steam boiler feed water drainage, or open the valve economizer recirculation tube to protect the economizer is not burning. Fourth, Kai, during shutdown lower furnace temperature, a solution of unburned fuel in the furnace: extinguishing device immediately put into vapor, carbon dioxide or other devices off fire. Five burning improperly adjusted, with insufficient wind or with the wind unreasonable Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan. These are the methods of electric heating steam boiler fast boiler to provide you with the handling of soot in the chimney, if you use electric steam boilers, with more than five can control their own boiler equipment need to be cleared up the flue, and select the appropriate method .

Importance of continuous Feedwater equipment in Gas-fired Steam BoilerThere are two kinds of feed water methods for steam boiler, steam feed water and electric feed water. Steam water supply equipment mainly refers to water injector and steam reciprocating pump, usually acting as backup water supply equipment in boiler. Another commonly used electric feed-water method is through the electric centrifugal pump and vortex pump to feed the water. During the operation of steam boiler, the feed water equipment is usually required to have the active control function. The water level can be lowered to a certain azimuth to actively open the pump to feed the boiler, and the inlet water to a certain direction can also actively stop the pump. Hot different types top fired water boilerss can also be recycled according to in / out water temperature or heating conditions. So gas boilers are usually equipped Use an electric centrifugal pump or vortex pump instead of steam-powered feed-water equipment. The feed-water equipment in gas-fired steam boiler is a very important equipment in all boiler systems. It is responsible for supplying raw materials to steam boilers; allowing it to produce the steam it needs to be used. In the process of boiler operation, it is necessary for the water supply equipment to run synchronously so as to supply water to the boiler continuously, so that the boiler can get enough water supply to run normally and safely.

Measures to improve the thermal efficiency of the fuel gas-fired 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.

Recently, Dezhou City, Shandong Province, has released the main points of pollution prevention and control in 2019, set specific targets and implement measures to control emissions of persistent pollutants SO2, NO2, to reduce the number of aspects such as severe pollution days.

1, continued to promote the total coal consumption control. Strictly implement the coal consumption reduction, equivalent alternative policy requirements. Continue to implement the monitoring and early warning mechanism to control the total amount of coal, coal consumption for the counties (cities, districts) were scheduled monthly, quarterly analysis, forecasting and early warning and timely release. Refined coal decomposition control mission objectives to ensure the completion of the annual total coal consumption control tasks.

2, strengthen renewable energy development and utilization. Actively promote wind, solar, biomass, geothermal and other renewable energy sources, promotion of power generation, industrial and residential heating and other heating applications.

After transformation of NOx emission in principle higher than 50mg / m3. Achieve a stable concentration of nitrogen oxide emissions rebuilt 30mg / m3 or less (that is, ultra-low NOx combustion requirements) can be appropriate priority in provincial subsidies make up ecological civilization prize funds.

5, continue to promote clean coal. Strengthen clean coal production, supply, construction and distribution system, and continue to improve the implementation of the subsidy policy, to ensure the timely distribution in place to protect the people warm winter. Bulk coal market to strengthen the comprehensive improvement of law enforcement, the implementation of three coal detection mechanism to prevent inflow of low-quality bulk coal, clean coal to ensure quality standards. 2019, on the basis of full coverage in clean coal, continue to promote clean coal.

6, strengthen high-pollution fuel combustion zone ban construction. Combustion zone ban, a ban on new or expanded high-polluting fuel burning facilities have been built to the deadline to switch to clean energy. Investigate and punish illegal construction, expansion and high-polluting fuel facilities are not completed within the prescribed period rectification behavior. Ban on burning coal for a total ban on the circulation area.

7, continue to promote clean heating transformation. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. Accelerate the pace of production, supply and storage of natural gas marketing system construction and gas storage facilities, improve air support capabilities. To develop multi-gas source, priority for clean heating, ensure safe and stable gas. Strengthen heating, gas facilities construction, expanding the central heating, gas, geothermal heating coverage.
