indonesia coal fired boiler
Two reasons for gas-fired indonesia coal fired boilers are widely used: various types of boilers, each boiler combined effects, although similar, but differ in the use and application requirements, and utilization of gas boilers in recent years, more and more, is widely used in various fields, thus it necessarily useful significant advantages and characteristics of the following article to do a comprehensive analysis of the two main reasons the gas boiler is widely used. First, in line with environmental standards, higher efficiency due to low gas other fuel gas boiler ash, sulfur and nitrogen than coal, burning more fully, and thus the amount of dust in the dust rarely, can greatly mitigate environmental pollution, and better meet the environmental requirements of modern production, on the other hand due to better overall environmental performance of a gas boiler, prompting the convection bank erosion bear small, good heat transfer, heat radiation and strong, low exhaust gas temperature, thermal efficiency is significantly improved, better use of effects to enhance the overall durability of the good gas boiler, prompting the two complement each other to produce the effect. Second, to reduce the manpower and costs, improve the overall output of the gas boiler ancillary equipment is not required on gas, Cleaner, Dust, grate and so on, saving equipment investment boilers. Better organized to improve the overall cost of gas boilers, gas boilers on the other hand the use of piped gas powered, no gas storage and other auxiliary work content, the better to reduce operating costs, operating cost savings, regular savings facilities contents spending could further reduce expenses related to the content of labor costs, to better enhance the overall output of the gas boiler.
Dongguan City, Guangdong Province in phasing out coal-fired indonesia coal fired boilers to replace the environmental transformation, biomass boilers in industries packaging, leather, clothing, textile and other widely used. However, biomass boilers still present drawbacks: If insufficient biomass combustion, typically generate a lot of dust, nitrogen oxides and other pollutants, improving PM2.5 concentration, air quality.
Dongguan City Atmospheric Office official said that since the Dongguan started Blue Sky Battle since, the city ton output capacity the courage to decisively eliminate those high pollution and high emissions industries and enterprises, won the majority of the masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity. In the eco-friendly background, out of high pollution equipment is the trend.
Transformation and upgrading of enterprises demand, government support policies have, inside and outside the echo, Dongguan out of biomass boilers into the fast lane. As of January 10, a biomass boiler out of the task of the city within 31 town street in Shilong, South City, the nave, Ma Yong, Hou Jie, stream, Feng Gang, Xie Gang, Chang Ping, Shek Pai, Chashan 11 Towns in the completion of the task of eliminating all living matter within the jurisdiction of the boiler. In addition, Long, Qi Shi, Tangxia, Sha Tin Kau five towns out of the completion of more than 90%, the remaining 15 Towns also have the confidence out of the task in the year 2019.
While out of the biomass boiler, Dongguan City, accelerate the pace of construction of gas pipeline to provide clean energy for the needs of the enterprise.
Atmospheric Office official admits:. "A few years ago, the city lags behind the construction of the gas pipeline, laying of pipe network coverage area of a small number of enterprises in the coal phase-out of high-polluting fuels, the use of biomass boilers as an interim energy supply equipment, there are also often allowed to change the fuel business, steal burning coal. "but now, due to the environmental protection departments to actively coordinate the town street, village (community), industrial areas, and vigorously promote the construction of natural gas pipeline, starting from the source to provide clean energy for businesses, stealing burn the behavior of coal is greatly reduced.
Over the past year, the city has a new natural gas pipeline 256.6 kilometers, 530 companies have security using natural gas. The city urban management department based on the actual distribution of useful gas needs of enterprises to develop business for the city's more than 600 natural gas pipeline construction plan and coordinate the new Austrian, Xinghua, often positive and three gas pipeline company to carry out construction work to ensure that the natural gas pipeline construction project smoothly, so that more companies access to clean energy as soon as possible.
According to statistics, date, Dongguan City gas pipeline or central heating station accessible area of 660 biomass boilers, has eliminated 572 units, 41 enterprises have to apply for the boiler out of subsidies.
Personnel and to avoid faulty gas indonesia coal fired boiler gas boiler prone to some fault in the use of the process in order to avoid it fails, we have to understand some of the considerations when using. When using a gas boiler, we should always carry out its care and maintenance of local failure timely maintenance and replacement, make sure it is working properly. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, and should be cleaned. Low temperature liquid phase heat carrier outlet of the furnace, for lack of heat, and the exhaust gas temperature exceeds 300 ℃, the main problem is the fouling, soot blowing should be. As low exhaust gas temperature, the main issue is burning, mainly lack of the wind. Although the pressure furnace, the blast volume is not open, the furnace temperature is low, combustion insufficient strength. We should focus on rear seal machine check furnace slag, dust, etc. whether closing the ash outlet is good, with or without cold air leakage into large. Before and after the filter differential pressure increases, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. Grate stuck. The reason is often broken or grate grate fall loose pins; coal grate has stuck to metallic inclusions; arched grate; slag filter (Eagles iron) sink tip and the grate stuck. Processing method: reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. The iron eagle sink, both sides can pull the fire door pull hook n. Grate stop turning, it may be too loose chain, and sprocket meshing well, or badly worn sprocket, and chain-linked bad; the adjustment screws on both sides to re-adjust the tension grate, if still does not work, you need to exchange sprocket.
Today I saw that when the capacity is the same, the furnace of the oil-fired indonesia coal fired boiler is smaller than that of the coal-fired boiler. Why? The specific reasons are as follows: the size of furnace volume, after the boiler capacity is determined, mainly depends on the volume of heat load. The size of the volumetric heat load is mainly determined by the type of fuel. After the fuel enters the furnace, it will take a certain amount of time to burn out. Fuel is usually required to burn out before it leaves the furnace. It is obvious that pulverized coal will burn longer than oil, that is, the flame of coal combustion will be longer than that of oil. In order to ensure the long-term safe operation of the boiler, it is necessary not only to prevent the slagging of the boiler, but also to make the temperature of the flue gas at the furnace outlet begin to change compared with the ash in the flue gas The temperature is 50 ℃ lower than 100 ℃ to prevent slagging at the furnace outlet and subsequent convection heating surfaces. The ash content of coal is more than that of coal-burning furnace, and the flue gas temperature of furnace outlet is 1050 ℃ and 1100 ℃. There is no danger of slagging in the furnace because of the low ash content in the oil, and do not consider the slagging problem of the slag discharge tube at the exit of the furnace, so the smoke temperature at the exit of the furnace can be higher.
