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.
Steam boilers are widely used in many companies, as are hot water boilers. A hot water boiler is a boiler that produces hot water. It refers to a thermal energy device that uses heat or other energy released by fuel combustion to heat water to a rated temperature. Hot water boilers can be widely used in power generation, heating, bathing, etc., and can also be used in enterprise production. The hot water boiler produced by CBM has been sold to more than 80 countries and regions in Russia, Mexico and Australia. Among them, hot water boilers are very competitive in Mexico.
Behind honor, it is thousands of times persist and exploration. Keep trying, and failed to improve, we have a number of scientific and technological problems. The launch of China's first low nitrogen boiler and stable operation in 2014, Beijing Huairou APEC venue for the realization of "APEC blue" to contribute their part. Respond positively to national policy, contribute to the cause of environmental protection. Group focus on lower nitrogen oxide emissions, a low nitrogen introduction of multi-type boiler. Existing "Thalia", "Willie sharp" and other series, the successful implementation of nitrogen oxide emissions below 18 mg / cubic meter, this data is far below the national existing standards (such as the most stringent in Beijing the implementation of 30 mg / cubic meter standard), is widely used in national important organs of the CPC Central Authority, the national Tourism Bureau.
Brief characteristics of coal-fired boilers and gas boilers difference: one is the most common category of boiler coal-fired boiler and gas boiler, although it is more consistent in showing the effectiveness of the integrated, but in the specific combustion, combustion products and there is a huge difference on the specific operating requirements and work processes, the following article will be brief characteristic differences coal-fired boilers and gas boilers for everyone. First, the coal-fired boiler combustion grate firing combustion, coal fired by a plane conveyor chain grate, complete combustion process in the furnace. While the combustion gas boiler combustion chamber, the gas is mixed with air in advance is set in proportion to the burner, injected into the furnace through a nozzle, the torch was installed in the furnace to complete combustion. Second, the automatic control of the force due to coal-fired boilers factors coal, coal seam thickness, the amount of blowing, the wind amount, and the air volume distribution grate speed limit, to be difficult to automatically adjust the operating parameters of the boiler according to the load. And high-quality gas boilers less impact on factors, may only be adjusted according to the size of the fire burner load, easy to achieve automatic control. Third, the combustion products of coal mainly by c, H, 0, N, and other elements composed of ash and water, but not the mechanical mixing of these components, but a very complex compound.
