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.
Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart. How early circulating fluidized bed boiler ignition achieve the protection of reheaters? Fire causes of valve failure chemical industry regulation and Countermeasures bearing parts heat treated high boiler common defects due to low bypass the security gate and reheaters failure phenomenon and treatment of condensate pump turbine worm gear failure cause analysis and improvement measures in the pneumatic valve powder operating system instructions on how to implement.
Industrial boilers and heating boilers What is the difference? Industrial boiler product in two ways, one steam used to generate electricity or gas, such as steam vaporized available fertilizer plant, coal as raw material, synthetic fertilizers, which is typical of industrial boilers, coal-fired industrial boilers still account for a large most gas is generally waste heat boiler for recovering waste heat. Industrial boilers commonly circulating fluidized bed boiler industrial boiler thermal power equipment is important, our country is today the world's largest production and use of boilers country. China's manufacturing industry is established and developed after the founding of New China. The term "industrial boiler" in the late 1930s, with the boiler thermal power generating units with capacity increasing, in order to distinguish high-capacity power plant boiler gradually adopted. Modern large-scale industrial boilers evaporation capacity has reached 100 to 200 tons / hour. Industrial boiler structure type in the structure can be divided into fire cartridge type, water and fire tube type 3 class. ① fire tube boilers; it is an early boilers, fire tube containing only water in the boiler twelve heating pot shell fire cylinder combustion means. Low thermal efficiency, large volume and steel consumption, since substantially no production 60s. ② fire tube boiler: it is in the vertical or horizontal potshell in addition to the fire tube, a plurality of means further smoke tube. The fuel in the combustion chamber high temperature flue gas produced after combustion smoke flows through these pipes heating pot of water, and then discharged into the chimney. Compared with fire tube boiler, since it is the number of multi-smoke tube, heated area increases, the exhaust gas temperature is low, high thermal efficiency, and the consumption of steel are relatively small volume of the boiler. FIG. 1 is a horizontal tempering tube boiler. When evaporation fire tube boiler is generally not more than 15 t /, working pressure not greater than 1.6 MPa, the thermal efficiency of coal is generally about 70%, of all oil-fired boiler automatic operation, the thermal efficiency can reach 85%. ③ water tube boilers: mostly used for larger capacity, higher pressure industrial boilers. Water tube boiler has a natural circulation type and DC two. Natural circulation water tube boiler with a single drum and double drum and other structures. Figure 2 is a double drum water tube boiler. Such boilers generally disposed in the convection tube economizer, an air preheater and sometimes, in order to reduce exhaust gas temperature. When coal efficiency up to 80% higher when the fuel. No drum DC industrial boilers, and the tubing coiled behind the inner wall of the furnace tubes of the convection heating surface composition. From the end of the tube into the water supply, the steam output from the other end. Industrial boilers small current, typically with separator and automatic control devices. The fuel and fuel combustion equipment is widely used in variety of industrial boilers, coal (bituminous coal, anthracite, lignite and coal waste, etc.), oil (heavy oil, residual oil and diesel, etc.), gas (natural gas or various industrial by-product gas) plant and urban waste (wood, bagasse, black liquor and waste, etc.) and so on. Therefore, industrial boiler combustion equipment is also varied. There layer belongs chain grate combustion apparatus, the feed grate, reciprocating grate, vibrating grate, chain grate stoker plus the like (see grate). Also useful way of fluidized bed combustion (see boiling furnace). In the evaporation of 65 t / h coal-fired industrial or larger capacity boilers generally use coal. Heating boilers boiler belongs to the category of civilian life, as people's safety awareness, and after 2000 are based on building heating hot water as heat medium, it does not allow the use of steam boilers, so in general we are talking about heating boilers often refers to pressure china wholesale coal fired hot water boiler. There are many types of heating boilers, their classification is mainly divided in accordance with the fuel type, fuel heating boilers can be divided according to the different electric heating boiler, oil heating boiler, gas heating boilers, coal-fired heating boilers, biomass heating boilers. Which includes fuel: diesel, kerosene and heavy oil; which includes gas: Natural gas, LPG, city gas and biogas.
