Coal fired circulating fluidized bed condensing r2 ton fired hot water boilers has simple and compact structure, the boiler body consist of combustion equipment, coal feeder, water cooling system, separators, economizers, air pre-heaters, steel frame, escalators, furnace walls and other components, adopt full steel frame.Coal fired circulating fluidized bed hot water boiler from the front to back are arranged in order as combustion chamber separators, tail flue, to ensure good sealing performance, high temperature zone with membrane wall sealing structure, all suspension type, fixed expansion center, dip leg is integrated with the furnace water wall for expansion, improve operating reliability and reduce heat loss, Before furnace is the coal feeder, combustion required air provided by the first and second fan, fuel combustion in the furnace produce flue gas that carrying some fuel, the separator is used to separate flue gas and fuel, the fuel through separation back to the combustion furnace. By adjusting the amount of coal, the primary air and secondary air flow rate and ratio, bed inventory, you can easily adjust temperature inside bed.

Industrial boiler energy-saving technological transformation of existing problems in industrial boiler energy-saving technological transformation of Question 1, the lack of innovation, application of energy-saving boiler mature, molding technology and equipment, such as: increased flue gas heat recovery unit, blowers inverter , condensate recovery and other conventional energy-saving measures is essentially a general condition; and the need for structural changes in energy-saving measures, such as fractional bed combustion of coal and boiler furnace arch transformation techniques, etc., are rare; as transformation project new principle, a new device, oxyfuel technology, high temperature air combustion technology, spray pulverized coal combustion technology (+ supernatant layer combustion boiler combustion mode), condensing heat recovery technology, new energy technologies dust ash and water treatment equipment, is very few. In general, innovation is not enough, the technical content needs to be improved. 2, part of the boiler is not fully considered in the transformation process, but simply changing the burner, the combustion gas flow distribution and does not match the corresponding surface of the heating boiler, the boiler furnace wall insulation and sealing transformation. There is poor combustion boiler, insufficient output, higher exhaust temperature problem, can not achieve the purpose of energy saving. 3, the waste heat boiler using high temperature organic heat required for thermal processes, a boiler generally at 200 ℃ 300 ℃, the exhaust gas temperature of the boiler is usually too high, excessive. In order to meet requirements of energy saving, companies often mounted in the boiler backpass evaporator or a hot water tank, flue gas waste heat recovery, reducing the exhaust temperature. But most of the heat generated in the production process does not require little energy. 4, statistical analysis of experimental data shows that there are many problems inefficiencies run natural gas boiler. The main concern of automatic combustion control, early production debugging is not in place, and so on. Gas boiler gas and incomplete combustion abnormal increase in heat loss caused by high temperature exhaust gas is the direct cause of poor operating efficiency. However, the use of clean energy natural gas boiler, generally higher thermal efficiency, energy saving difficult. Corporate restructuring investment funds enthusiasm is not high.
Classification of Oil-fired BoilerCompared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Fuel-fired boilers are heated by burners, and fuel-fired atomization effects Good fuel combustion, smokestack can not see black smoke, so fuel-fired boiler green, efficient and energy-saving. Oil-fired boilers include oil-fired water boilers, oil-fired condensing r2 ton fired hot water boilerss, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil.
Fuel-fired boilers that produce steam, hot water, or thermal liquids for direct or indirect use; Furnaces, or it may be direct-fired using fuel gas or electric resistance. Gas heaters require proper venting and safety controls. hot and condensing water, and brine. They are also used for pumping steam condensate and for boiler feed.Get A Quote

Flue gas desulphurisation is now being studied. Two or three processes will be compared in the course of the coming year. With regard to the NO x-production, the coal-fired boilers are tangentially fired and generate only about 400-600 ppm NO x on a volume basis or about 250-375 g/GJ, whereas opposed front firing boilers produce about 300-500 g/GJ.Get A Quote
