factory direct coal szl boiler

Several countries because of pressure cast iron factory direct coal szl boiler efficiency indicators have been carried out in a blaze of glory roaring coal to gas work, use cast iron boiler, greatly minus the dust of the infected, and dangerous gases such as nitric oxide smoke It has been suppressed. Efficiency index is a measure of the key rules of cast iron boilers, here we come to discuss under pressure cast iron boiler efficiency indicators of several reasons. After research stakeholders, cast iron boilers heat loss stems from two main places: the loss of full combustion air ratio unreasonable and smoke exhaust heat. Heat loss can be reduced smoke emission can be converted flue gas heat recovery boiler of cast iron fitted in the tail, or selection of more excellent function FGR boiler. Fully air combustion ratio does not meet the criteria unreasonable Summary: ordinary cast iron boilers ejector burner, resulting in air-fuel ratio can not be motorized mobility. Many cast iron boilers are mechanical draft burners, resulting in an unreasonable fuel ratio because of the following: the main air-fuel ratio unreasonable case two types: when too much air, not having excessively low temperature air is heated , resulting in cast iron boiler energy costs rising, cast iron boiler efficiency index weakened; when there is insufficient air, insufficient burning situation occurs, resulting in cast iron boiler efficiency indicators weakened.

Advantages of heating Boiler and Gas-fired heating BoilerOil-fired and gas-fired heating factory direct coal szl boilers all belong to chamber-fired boilers. The fuels used are injected into the furnace by burners and no cinder will be produced after combustion. This type of heating boiler does not require the complex and huge crushing of coal-fired boilers, facilities for conveying tender coal and equipment for burning and dedusting, so it is compact in structure, small in size, light in weight, small in land area, small in pollution and high in automation. Cities and boiler houses that require high environmental protection and prohibit the use of coal-fired boilers are used in large quantities in areas and units with high technical requirements for heating regulation. Medium and small boilers generally use light diesel oil, large-scale oil-fired boilers burn more heavy oil. Due to combustion The boiling point of oil is always lower than its ignition point, so the fuel is usually gaseous. After heating, the fuel is vaporized into oil vapor. After the mixture with air reaches a certain temperature, it starts to ignite and burn. In order to enhance the degree of vaporization of fuel, the fuel is often atomized into small droplets into a man-made furnace, heated by high-temperature flue gas in the furnace, and quickly vaporized and mixed with oxygen in the surrounding air, starting to ignite and burn. Some of the heat after burning is passed to the oil droplets, which vaporize and burn until they are exhausted.

The reason the gas factory direct coal szl 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.

Lujiang County, Anhui Province People's Government to strengthen the special equipment safety supervision, eliminate security risks, protect people's lives and property safety, recently, market supervision arrangements father of the rule of the mountain to carry out a special inspection of the factory direct coal szl boiler.

The area under the jurisdiction, boiler unit 10, involving 13 sets of boilers, mainly for industrial enterprises, food production enterprises. The audit focused on with the operation of the boiler, the boiler nature of the situation (coal, electricity, gas, biomass, etc.), verification test cases, water quality monitoring, troubleshooting, case workers certified, the implementation of the system, etc. . Examination revealed there is some use of units overdue inspection, the main responsibility is not implemented and so on, law enforcement officials immediately issued special equipment safety supervision instructions, the use of units ordered to stop using, to urge the rectification.
