domestic used gas boilers

Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam domestic used boilers for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.

What is the excess air coefficient of domestic used boilers and boiler professionals work? Learning and understanding of the boiler, the following is mainly to answer some specific questions, which specifically is: What is the excess air ratio boiler? Its smoke is calculated, and what about? And, What are two boilers, not within the scope of supervisory inspection? Designed boiler work, which refers to what? What are the contents of their work? So, the next immediately to give a specific answer. 1. What is the excess air ratio boiler? Its smoke is calculated, and what about? Boiler excess air ratio, for the noun words, simply, is a boiler operation, the ratio between the actual and theoretical air consumption air consumption. For different types of boilers, it is not the same. For example, oil and gas furnace is 1.1, and the fluidized bed boiler, it is 1.1 to 1.2. As for the calculation of flue gas boiler, mainly related to combustion equipment type and fuel type two.

Method of reducing the exhaust gas temperature of the domestic used boilers which: standard boiler exhaust gas temperature: between the boiler flue gas temperature of 200-230 deg.] C in accordance with conventional design national standard thermodynamic calculation boiler design requirements. Conventional exhaust gas temperature selected reasons, coal fired boiler combustion process will produce a certain amount of SO2, and SO2 below 170 ℃ will bind and generating flue gas H2O H2SO4 sulfuric acid, H2SO4 sulfuric acid and will form boiler heating surface of tail corrosion, thereby reducing the life of the boiler, conventional coal-fired boiler exhaust gas temperature is higher than 200 ℃. Temperature is high energy loss and more, is not conducive to energy saving. Cooling measures taken to ①, the economizer application: increasing the boiler economizer (economizer) of heat transfer area, larger than the conventional take about 1-2 times the flow cross sectional area economizer structure, effectively reduce smoke flow rate, to strengthen the heat transfer efficiency, reduce exhaust gas temperature; ②, air preheater applications: pipes connected to the air preheater economizer disposed, the apparatus can effectively increase the temperature of the combustion air, improving the ignition of the fuel condition. Very beneficial to the boiler combustion conditions. ③, adjust bidirectionality combustion system, a boiler originally designed for fuel specifications have some flexibility, different media in effect outside the combustion process are different, adjusting the embodiment, with the economizer and the air preheater using, the temperature of the boiler exhaust emission control at a suitable temperature, that make full use of heat energy, but also to ensure the integrity of the structure and function of the relative equipment, environmental protection, energy saving, security and development is the social responsibility of all of us for a rational design of industrial structure boiler, thermal efficiency is relatively high, its emissions would be relatively low temperatures, so we must be careful when choosing a boiler boiler property report form.

Advantage of Oil Boiler

Availability: Oil is popular in places where natural gas isn’t readily available. Maybe you don’t have gas in your neighborhood, or maybe your house isn’t connected to the gas line. With oil, that’s not an issue, because as long as there’s an oil provider near you, you can order, get delivered, and store oil for your boiler.
