scale and sludge formation in boilers
Dongguan City, Guangdong Province in phasing out coal-fired scale and sludge formation in boilerss 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masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity.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.
Does the hot water scale and sludge formation in boilers have to do some preparatory work before purchasing?
From a professional point of view, the hot water boiler needs to do some preparatory work before the product is purchased, which can reflect the importance of the purchase of the product and avoid the wrong choice. Moreover, it must be taken seriously and carried out, because if there is a problem, it will affect the correct purchase of the product. In the work content, in addition to a clear understanding of the product use environment and use requirements, but also to understand some basic information of the product and the manufacturer, so that multi-party comparison and comprehensive considerations, so that you have accurate judgment and correct choice.
Using Method 2 tons of gas steam scale and sludge formation in boilers 1, to check before the start of attachment deaerator water level control valve, water level alarm, steam pressure control valve, seal means (previously filled with water) and a variety of instrumentation has been in the supervision normal state, does not meet the operational requirements should be adjusted. 2, slowly start the pump inlet, inlet temperature and pressure recording. 3, the water level regulating valve before the valve is opened, the bypass valve is closed. 4, the exhaust valve slightly open top. 5, opening the upper valve tube steam heating tank, the heating temperature in the tank. 6, the valve is opened the steam pressure regulating valve for steam heating, inlet pressure and temperature recording 7, when the water level has reached the level indicated in Table normal level (1/2 water gauge), a thermometer indicator tank is about 104 deg.] C, starting feed pump, open the water supply valve, from start to normal supply about half an hour. 8, deaerator during normal operation, the upper portion of the exhaust valve opening degree of about 1/4 turn around. 9, the steam supply valve is closed upper deaerator steam heating tubes. 10, at regular intervals laboratory water, water's oxygen content, record the value of various supervision instruments
Xuchang has cheap and practical steam scale and sludge formation in boilerss do? Select steam boiler more than you? Boiler equipment, now has always been the traditional equipment, such equipment, the role it plays is that you can in the winter time, able to supply heating and hot water, can become today's factories, schools, hospitals, etc. will be used to place the device, people can become aware of the device. Of course, this boiler equipment, also has a gas-fired boiler, electric boiler and so on.
