Steam boiler has brought great convenience to industry. Steam boiler has driven the development of the times. The following is a brief introduction to the structural characteristics and working principle of steam boiler. Steam boiler is a machine that mainly produces steam, and many people use it, but many of them do not know much about its structure and working principle. It makes use of coal, oil, natural gas and other water-tube steam boilers with limited capacity and pressure. There is a large desire to space, and easy to arrange, steam boiler in a variety of forms. Water is heated in the drum into steam, and the heat emitted by fire in the furnace is the principle of a steam boiler. Work of steam boiler Principle:
1, the heat generated by pulverized coal combustion in the furnace is first absorbed by the water wall through radiative heat transfer, and the water boiling of the water wall is vaporized, producing a large amount of steam into the steam drum for steam separation (except for direct flow furnaces). The separated saturated steam enters the superheater and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and the tail flue through radiation and convection, and enables the superheated steam to reach the required working temperature. The steam boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work, and the reheat steam comes out of the reheater to go back to the middle, and the low-pressure cylinder continues to do the work to generate electricity.
2. When the pulverized coal stove is working, The position of the center of the flame will affect the amount of evaporation, generally speaking, if the center of the flame is low, the amount of evaporation will be large, and the position of the center of the flame will also affect the temperature of the superheated steam or reheated steam, as well as the high value of the flame center and the small amount of evaporation. When the flame center is low, the superheated steam, especially the reheated steam temperature, will be low and vice versa.
3, the arrangement of burners, as far as coal powder furnace is concerned, there are many kinds of combustion modes, such as front and rear wall, tangential combustion, double tangential combustion, and so on, each of which has its own characteristics. The influence on steam can not be directly determined because the same furnace can not apply the above-mentioned arrangement methods at the same time.
Steam boiler preventive measures introduced Common Failures and precautions 3th fired steam boiler for brewing and steam reciprocating pump 1. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Near the steam boiler room should be equipped with adequate and effective fire fighting equipment. 2. Steam boiler room must have staff on duty 24 hours, the guards take turns, and always check the water level in the boiler, in order to ensure that it is above the safety line to prevent an explosion caused by burning dry. If the fire operation in explosive areas must obtain a work permit fire and take adequate fire safety measures in order to carry out fire work. When the fire should send someone on duty at all times observe the fire situation. 3. A storage vessel containing the non-flammable gas in the boiler room. 4. The staff of steam boiler room must be certified before the arrival of the boiler and proficient technique, it has a certain capacity to detect and recognize security risks. 5. If the boiler safety on a regular basis in accordance with the boiler maintenance procedures, should be carefully examine each of insecurity in the inspection process. 6. Distribution Line steam boiler room disposed defective safety device using a metal tube or pipe nonflammable hard plastic protection switch box should be installed outside the boiler room, respectively, to achieve power, should be prohibited. 1. What is the reason there is no discharge of steam reciprocating pump is? How, how? A: (1) Failure: 1 suction or discharge pipe blockage. (2) out of the stuck valve. There is an air cylinder. (4) a suction tube connected lax. (5) column (live) seriously damaged piston ring. (2) Method excluded: (1) exclusion of pipe blockage. (2) Remove the inlet, the outlet valve on the plug. (3) filled with water, the air is discharged. (4) fastening the pipe. (5) Replace Column (live) piston ring.
Application of electric 3th fired steam boiler for brewing steam boiler in the electrical industry applications in various industries ironing washing industry: dry-cleaning machine, dryer, washing machine, dryer, ironing machine, iron, and other equipment for use. Food Machinery Industry: supporting tofu machine, steamer, pot sterilization, packaging machines, coating equipment, sealing machine, and other equipment to use.

Other industries :( oil, automobile) steam cleaning industry (hotels, dormitories, schools, mixing station) hot water supply, (bridges, railways) concrete curing, (casual beauty club) sauna, hot swap equipment.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing 3th fired steam boiler for brewing for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.Free Chat
