The reason the gas best coal fired utility boiler to replace coal-fired boilers with the improvement of economic level, gas boiler to replace the coal-fired boilers, which causes the occurrence of this phenomenon it? Following small for everyone to introduce specific: 1, coal-fired boilers generally high cost, complex structure, low thermal efficiency, work slow, operating strength, requires a lot of memory and storage of coal ash sites, and the need for coal pulverized material, curing, preventing many complicated procedures and spontaneous combustion. 2, with the popularization and development of gas industry, some coal-fired boiler to gas fired boiler, although the effect is an improvement over all aspects of coal-fired boilers, but obviously with a lot of deficiencies, from the installation of the burner into the furnace, convection bank arrangement and exhaust system must accommodate the original coal-fired boiler, so the overall effect is far better than gas-fired boiler professionally designed. 3, many coal-fired boilers because of the long time use, it has been a lot of problems in the use of effects and economic terms. 4, and with increasing heating resident population of the region, the heat load of the boiler has become a serious shortage, making a lot of resident households reach room temperature heating requirements, the inconvenience to residents. 5, taking into account safety and environmental factors we have to consider its alternatives - the development prospects of the gas boiler. These are the causes of knowledge on gas-fired boiler to replace coal-fired boilers, and you also have a lot of harvest it the same with small series? I hope this helps you make better use of gas-fired boiler.
Do you want to install a new best coal fired utility boiler boiler cleaning and what is the Expansion? Circulating fluidized bed boiler coking, and what specific species are? Newly installed boiler, it needs to clean it? Also, what is the boiler Expansion? These are part of this important site boiler product, so the following will give the corresponding answer, and at the same time, so that we can have a good learning outcomes, but can also deepen familiarity and level of understanding of the boiler. 1. circulating fluidized bed boiler coking, there are specific what kind? Circulating fluidized bed boiler coking, which specifically then, there are high and low temperature coke these two, and, regardless of high-temperature coke is low coke, which coke temperature of the portion, are higher than the coking temperature of the ash . And in the specific temperature, it is to look at the specific types of coal. 2. The newly installed boiler, it is necessary to clean it? Newly installed boiler, it is required to do some work in order to start using. However, it is not clean, but rather cook stove, the boiler body in oil and other cleaned to prevent them appear soft drinks were vacated, in the course of this phenomenon problem. Further, in the oven cooking process, but also may cause the passivated metal surface, forming a layer of oxide film, thereby preventing the oxidation of the metal.
Industrial best coal fired utility boilers is a major driving force for social development, but also brought great pressure on the environment. Whether coal-fired boilers, biomass boilers, or, when the supply of energy, the emission of pollutants will soot and nitrogen oxides. Some enterprises in order to save costs, the pursuit of more profits, but also allowed to change the fuel, biomass boilers burning coal steal, wood, and even garbage doping or other industrial waste, produce dioxins and other carcinogens directly into the atmosphere after combustion, pushing PM2.5 concentrations.
Since started Blue Sky Battle horn Guangdong Province, many cities have begun to respond positively, Dongguan City, is one of them. Atmospheric do in-depth business thoroughly, and the development of industrial boilers business accounting, confirming the city's need to eliminate highly polluting boilers have 765 units, of which 728 sets of biomass boilers, 37 coal-fired boilers. Subsequently, promote the transformation of facilities operations out of high pollution boilers within the city.
As of May 14, 2019, the city's 324 enterprises active removal of 363 coal-fired boilers burning biomass, as well as 83 to 84 companies demolition of the old boiler pipes, 447 completed phase-out plan of the boiler in advance.
Although there are many companies take the initiative to carry the main responsibility for the ecological environment, but there are still some chances enterprise.
Atmospheric Office official admitted that "in the daily inspection, the company found that some still illegal use of boilers, perfunctory 'coal to gas' work." Among them, although some enterprises written off coal, biomass fired boilers, but because of natural gas boiler installation behind schedule, forced production needs, but to let the old boiler continues posts. There are companies more "capricious", install two-way pipeline for new and old boilers, strict supervision when using gas-fired, law enforcement officers continue to take a coal burning biomass. There are even companies deliberately delayed "from coal to gas," progress, choose to enable the original write-off of the boiler.
This year, the Office of Atmospheric inspection personnel to go to 244 companies in the field to check the boiler usage, found that 42 enterprises there is illegal use of boiler problems. Among them, there are 18 companies of illegal use of biomass boilers has been canceled. "Not only pollute the atmosphere, there are still significant safety risks." Atmospheric Office inspection personnel Lurui Quan said, "the city's coal-fired, burning biomass boilers as well as 113 units, involving 94 companies, is expected to complete phase-out year, access to clean energy. "simple behind the data, there is a thick ledger out of the transformation of the boiler," when removed, when write-off, out of a pin number one glance. "
Atmospheric Office official also said the recent city towns Street (Park) Atmospheric Office will carry out investigation and remediation special action has been canceled boiler, supervise and guide enterprises to demolish the old boilers and pipes, put an end to "note not sell" phenomenon. At the same time, urge enterprises will have been dismantled boiler dedicated to the sale of scrap recycling company, effective way to solve the old boiler, complete eradication of pollution and safety hazards.
Because of the characteristics of domestic resource structure coal once had a large proportion in the resource structure so the coal-fired best coal fired utility boiler was also in a prominent position in the market. However, with the change of resource structure and environmental pollution in recent years, gas-fired boilers are gradually replacing coal-fired boilers and becoming the main force of the new market because of their natural advantages. Gas-fired boiler market is gradually obvious, has its own obvious advantages, the following comparative analysis of the advantages of gas-fired boilers. Gas-fired boilers are fueled by natural gas, which burns rapidly and produces great power, so it is also efficient, and its efficiency is 50% higher than that of coal-fired boilers. . Although natural gas prices are higher than coal prices, apart from the cost of fuel, as long as the pipeline can be invested. Coal-fired boilers, in addition to fuel costs, transportation costs, labor costs, storage costs, etc., the overall price is not cheap. Therefore, from the cost-effective point of view, natural gas as a whole has more advantages. Natural gas is one of the most environmentally friendly sources of energy by far because of its abundant combustion, clean combustion and pollution-free emissions. Coal combustion emissions sulfur, ash content is more serious pollution to the environment, which is also incomparable with gas-fired boiler. Gas-fired boilers can bring greater environmental benefits to enterprises.
Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas.Get a Quote
