The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC coal fired boiler generate steam steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type coal fired boiler generate steam paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
Gas-fired steam coal fired boiler generate steam steam boiler gas to become the market trend is for countries to protect the environment, to control environmental deterioration and promote the steam boiler, gas steam boiler reconstruction is an arduous and urgent major project. Why the high price of coal to gas has changed, serious pollution of coal, especially in the past two years haze is particularly serious, mainly from coal to gas deal with environmental pollution, but the operating cost is much higher than gas. But the long-term development, economic development and should not expense of the environment, protecting the environment is everyone's responsibility. After gas steam boiler into a gas steam boilers, gas consumption is how much? Do not control coal, substantially in accordance with your boiler power to calculate, but one thing you need to think clearly, with the efficiency of gas-fired boiler efficiency gas boilers were quite different. So when you change 4 tons of coal boiler gas boiler, you can consider using a smaller gas-fired boiler. Coal to gas is a national policy not to install all right? Not installed, then it is possible, but now the country for gas-fired boilers is gradually ban, not to use, and if you do not choose coal to gas, then you need to select the coal to electricity, coal to heat pump etc., the gas must be slipping, these types of coal to the way you can compare each to see which is more suitable for their own gas steam boiler steam boiler gas into the benefits of what. Gas steam boiler includes a central water heater, new energy-saving, high efficiency stainless steel burner, electronic ignition pulse, a stainless steel coil heat exchanger, a strong discharge blower, intelligent control assembly elements, security devices and the like, the use of liquefied petroleum gas, natural gas, gas and other gaseous fuels, using the latest combustion technology design and manufacture of the heat exchanger, the thermal efficiency up to 95% water fast heating speed, high flow, with energy saving, easy to scale, automatic control without staff on duty, easy maintenance and so on. Economic and environmental performance far superior to the conventional type boiler modules may be stand-alone or in combination of line. Gas-fired steam boiler to save land resources, the same will not cause pollution like soot gas boiler. Gas boiler need to go through dust, slag process, complicated process, where the same water, gas boiler more environmentally friendly.
The transformation of low nitrogen coal fired boiler generate steam should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.Free Chat
