Center back 2019 boiler prices fired 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 boiler SZS improve thermal efficiency because the oil, gas type SZS easy to burn the fuel 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.
The difference between fuel gas 2019 boiler prices fired boilers and oil-fired boiler fuel boiler is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, methane, etc.), depending on what fuel fired boiler combustion device called , a configuration called gas burner boiler gas boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference lies in the use of fuel burners burn anything.
What differences have low nitrogen 2019 boiler prices fired boiler with ordinary boilers? We all know now the boiler furnace oil and gas market sell very popular, especially for low NOx combustion of furnace oil and gas is in short supply. However, for many boiler manufacturers, the low nitrogen technology is even more difficult to overcome the problem, the birth of low nitrogen boiler is a milestone, a professional low nitrogen furnace boiler developed by the company's low-NOx combustion technology has been widely used in the industrial boiler application. 1, since the difference in emission layer burning combustion mode, combustion chamber, different circulating fluidized bed boiler, the furnace in different structures, the original NOx emissions which there are large differences, in general, not specifically for low NOX combustion furnace technology employed when , circulating fluidized bed low NOx raw emissions, NOx emissions to the original furnace chain represented slightly lower layer burner, pulverized coal-fired boilers industrial boilers room, the higher the NOx emissions original, well-known low nitrogen emissions from boilers are but Greatly reduced. 2, the different layers combustion boiler technology, combustion chamber, circulating fluidized bed boiler may be different with different low NOx combustion technique in accordance with the combustion mode, the combustion boiler for the air distribution layers using an air classifier, and more often to achieve low nitrogen Gas Recirculation combustion; under typical flue gas recirculation layer influence combustion boiler combustion zone, in conjunction with the air fractionation techniques for reducing NOx by catalytic char; super reduction furnace denitration technology in recent years, new furnace denitration technology, by combustion reasonable location of the flame spray region ammonia, direct denitration at a high temperature flame. Low Nitrogen mainly the secondary air boiler, the coal to the location and distribution of optimal adjustment of the mouth, or the like to increase the flue gas recirculation system. 3, at different central security layer after combustion, combustion chamber, low-NOx combustion furnace circulating fluidized bed boiler technology a large number of tests performed, it has been verified in engineering applications, in general, a low nitrogen boiler to safety higher, the reason why in recent years, its sales volume increasing, there are many users because of its high security, a small threat to the space environment to buy, and this is one of its important differences with ordinary boilers.
March 22 to 23, Ganzhou City, Jiangxi Province Bureau of Quality Supervision established party leadership team, the progress of the 2018 phase-out of coal-fired 2019 boiler prices fired boilers to conduct random work. Leading group led by Liu Ping, deputy director of Ganzhou City, Municipal Quality Supervision Bureau, the Municipal Industry and Information Commission, the Municipal Environmental Protection Bureau and the Municipal Development and Reform Commission composed of four departments jointly checks group within Xinfeng County of Ganzhou City, Nankang District, Jiangxi counties and carried out spot checks Yudu County coal-fired boilers working-out of a total of 17 companies.
Sampling results show that 17 companies, more than 10 companies to complete phase-out of coal-fired boilers, the other seven unfinished business executives also said that this year will be to complete the rectification work before December 20.
In this sampling event, checks the group also proposed rectification direction of the coal-fired boilers for local authorities: by strengthening the policy advocacy, strengthening inter-site inspectors guidance and strengthen departmental interaction, the three parties work together to ensure the timely completion of this non-compliance within Ganzhou coal-fired boiler out of the task.Free Chat
