Gas-fired horizontal coal 2tph steam boiler price principle gas steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and which is vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source. Boiler and boiler shell consists of two main furnace and ensure accessories, ancillary equipment instrumentation, control and protection system safe and economic operation of its continuous constituted. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. The basic components of a steam boiler and a steam boiler operating principle is constituted by a series of devices can be roughly divided into two main parts and auxiliary equipment. The main components of the boiler are: 1. Furnace: fuel burn-up and ensures that the boiler outlet gas temperature to a value of convection heating surface cooled safe work; 2, economizer: utilizing the heat of the flue boiler feedwater heating, to reduce the exhaust gas temperature, fuel economy and functions. 3, the drum: the respective heating surface and joined together and the boiler water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 4, water wall: mainly radiation heating surface of the boiler, the absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 5, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion; 6, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reduced exhaust tobacco temperature, increase boiler efficiency. 7, the furnace walls: a housing to protect the boiler, since sealing and insulation. Heavy furnace wall of the small boiler may also function as a support member boiler. 8, the frame: a support member and the fixing boilers, Purple east 15:33:06 boiler auxiliary equipment are: 1, the wind equipment: induced draft fan and chimney via the flue gas generated in boiler operation sent to the atmosphere. 2, dust removal equipment: removing fly ash in the boiler flue gas. 3, the fuel supply equipment: fuel storage and transportation functions. 4, water supply equipment: water pump water supply through the water into the boiler by the processing device to. 5. Dust Cleaner equipment: removing ash from the boiler and carried away. 6, the blower device: by the air blower after exports the furnace air preheater and a coal grinding device heating applications. 7, the automatic control device: automatic detection, process control, automatic protection and automatic adjustment. IMPORTANT boiler maintenance and a maintenance, water maintenance method 1. The boiler must be a qualified treatment, which is to extend the life of the boiler, ensure the safe operation of the gas and steam. 2. The water temperature should be close to the furnace temperature, preferably above 20 ℃. 3. The need for low-water cutoff periodically inspect maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4. require periodic blowdown operation, daily (per shift) at least once, after the sewage drain valve should be checked whether the influence by dirt and leaks; if it must be excluded. 5. Shutdown the steam pressure is not maintained, the boiler will produce steam space negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened. 6. smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.
At any time, domestic more and more attention to environmental protection, coal-fired horizontal coal 2tph steam boiler price suffered heavy damage. Relatively speaking, gas-fired steam boiler is favored by many users. In recent years, the state has also vigorously promoted the use of gas-fired boilers. What are the benefits of a coal-fired steam boiler? Let's discuss it with you today. Gas-fired steam boilers and coal-fired steam boilers occupy half of the market, showing a trend of court resistance, but in the long run, gas-fired steam boilers will obviously become the only dominant market. No, please look! 1. Procurement cost: it is clear that gas-fired boilers are well ahead of ignition in terms of technology and ancillary equipment The coal boiler is equipped with a special gas burner. Take 1 ton steam boiler as an example, gas-fired boiler is about 30% higher than coal-fired boiler. 2. Construction cost: this cost mainly comes from boiler room. Because of the coal-fired steam boiler supporting equipment more, boiler room construction should invest more funds. The auxiliary equipment of gas-fired boiler has few auxiliary equipment, automatic control operation, automatic alarm and automatic protection function, which not only saves the cost of building, but also is safe and reliable. After connecting the natural gas pipeline, the burner will automatically supply gas, which can effectively save staff costs. Coal-fired boilers also have to pay some of their employees' salaries because they need to participate in the coal program . 3. Fuel costs: you can see this clearly by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. Environmental costs: with the need to protect the environment, the audit of coal-fired boilers is becoming more and more stringent. Gas-fired steam boilers are more and more widely used due to economic operation, environmental protection and energy conservation, as well as government policies.
Recently, located in Yan'an City, Shaanxi Province, Huanglong held removal of coal-fired boilers mobilization meeting, and promote the coal-fired boiler, "clear" work, Huanglong improve the overall air quality of the environment. The meeting was chaired by the Deputy Mayor Cao Zengjun, County Authority, Environmental Protection Agency, the Public Security Bureau and other coal-fired boilers Chaigai leading group members of the unit involved in coal-fired boilers and Chaigai of 16 enterprises and units attended the meeting.
At the meeting, urban management bureau announced the "urban transformation of coal-fired boiler demolition plan", and county coal-fired boiler demolition work arrangements for the deployment.
