1 4mw Coal Hot Water Boiler

Effect of boiler fine coal combustion boiler operating principle is to use thermal energy or heat in industrial post fuel released by combustion is transferred to the water in the container, the temperature or pressure of the water reaches a certain desired steam heating equipment. Many people will feel that coal-fired boiler more detailed the better, but is it really? From a combustion point of view, the finer coal particles more easily form a good mixing with the air, the more complete the combustion. But the coal particles too small, for boilers, milling power consumption will be greatly increased. Industrial boiler, the coal into the furnace too small, there will be the following questions: 1, coal leakage losses, etc. from grate gap increased. 2, boiler grate to be at full speed, power consumption increases. 3, fly ash, fuel loss increases. 4, a coal burning ember i.e., unstable combustion, furnace volume heat load difficult to sustain stable. So the boiler when using fine particles of coal, coal is subject to how much water, raw coal water, play groups and then into the furnace. If the burning coal of 8 to 12h before the water, so that the penetration of moisture into the interior of the coal particles is better. Water vapor produced is moistened triatomic gases, flue gas can strengthen radiation, facilitate ignition, exhaust and reduce heat loss

Low temperature corrosion of boiler fuel than coal-fired boilers serious reason these days after another customer asked why there are low-temperature corrosion of boiler fuel serious than coal-fired boilers, small and together we discuss in this article address this issue. When little understanding of the chemistry of you might know equal sulfur content greater body oil and coal, but asked what the low-temperature corrosion of boiler fuel in general it is much more serious than the coal-fired boilers? For two main reasons: a coal-fired boiler, pulverized coal fired boiler in particular, 90% of the coal ash in the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed by fly ash in the flue gas, so that the smoke sulfuric acid vapor in the gas is reduced; coal combustion, about half of the sulfur remaining in the ash. While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content fuel oil in the boiler, about 11% to 12%, combustion can produce about one ton per ton of fuel vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because it contains more water exception table below. Above the dew point of water vapor in the flue gas so that the fuel for two reasons, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1 shown in FIG. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to the fuel, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, not to say in small series, we will come to a low temperature corrosion of boiler fuel ratio of coal-fired boiler this conclusion is serious.

Install the latest modern boiler installation process is what: Although many places are using the water heater, gas may be, it could be solar, but the boiler installation still visible in people's lives everywhere. Boiler now than before, need to use wood or coal combustion energy generated by water heating, boiler now mostly use electricity, heating time not only fast, but also do not need people waiting at any time around it's a, and the control of water temperature and more accurate the.

To protect the economic development of enterprises, production safety running smoothly, according to Qingyang County in Anhui Chizhou municipal government air pollution control requirements, coal-fired boiler inspection pull the plug on a regular basis in October 2018.

Qingyang County Market Supervisory Authority for the county a number of companies were visited research to understand the company's current production operating conditions and problems, start from regulatory functions, for enterprise development to provide quality services, reduce business costs.

Special equipment boiler pressure is high risk, than a regular inspection cycle must immediately stop using, but they are also necessary for the production of business equipment, once the shutdown enterprises will face shutdown. Looking at business owners anxious eyes and counties actively discussing with the city center expert special inspection, and according to regulations, to quickly determine a set of effective programs and promptly inform each enterprise.

Through contact with the surrounding counties and cities to understand the relevant units of the boiler fuel change fees and counties take the initiative and boiler companies approached agreed upon with the use of rehabilitation programs, a significant reduction in transformation costs. Up to now, Qingyang County has completed 12 boiler fuel change work, the cumulative cost of more than 60 million.
