Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.
"Henan 2018 campaign of air pollution control plan" recently introduced, to guide and encourage medium-sized coal-fired boilers eliminated. In the province's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers.
Financial awards complement the way:
1, the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;
2, the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;
3, the completion of the coal-fired boiler Chaigai before the end of October 2020 no longer give financial awards complement.
Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
Oil-fired boiler safety instructions oil-fired boiler is one of many hot water boiler to one of how to prevent boiler fuel boiler appears to be abnormal use it? First, to ensure the normal operation of the fuel in the boiler feed water quality and quality of qualified soda, to reduce the water wall tube fouling and corrosion, strengthen supervision and boiler water boiler water when found unqualified, should increase the number of times a given row; while the flue gas flow rate control , especially when the flue gas velocity in the corridor, during installation and servicing, should minimize the distance between the wall and the superheater tubes, while the distance between the tubes to uniformly as possible. second, the fuel boost heating boiler carried out in strict accordance with procedures, control the speed boost. were lower header sewage water wall work required to build the water cycle as soon as possible, promptly switched the gun to ensure uniform heating surface is heated to eliminate half of combustion, eliminating thermal excursions. third, do a good job adjusting fuel combustion boiler, the flame deflection preventing, controlling coal fineness noted that, with a reasonable air to prevent coking, reduces thermal excursions, to prevent the tail reburning fuel boiler; boiler steam parameters be closely monitored, and the main indicators of the amount of water evaporation and the like, to prevent pressure Release, full of water, water accident. fourth, strengthening sootblower sootblower and management, serious fouling preventing heating surface, when there is found furnace coking phenomenon, should be increased blowing Gray times, ensuring good water wall heat sink; overheating problem of the presence of long-term heating surface, installation of thermal supervision controlling temperature measuring points; expansion to ensure accurate indication means using oil-fired boiler units must be fully taken into account the safety problems. in the inspection process must be meticulous in place. to ensure the personal safety of the unit.
How how electric hk town commercial steam boilers maintenance electric steam boiler maintenance 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, electric steam boilers stop running long time, turn off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, with a slow fire the burner drying pot (burning time not too long, to avoid damage to the boiler), then all of the drained gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.
