coal fired hot water boiler cost
Coal fired watertube boiler is a type of coal fired boiler in which water circulates in tubes heated externally by the fire. Coal fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. ZG Boiler manufactures coal fired firetube boiler and watertube boiler for sales. In Aug 2014, our company exported a set of 15 ton SZL coal fired firetube boiler to Thailand, an paper factory.

If there is damage in the supposed gas-fired? Detailed inspection is important, as the key oil regulation. According to the conditions and time management, gas-fired, people can effectively damage inspection program. The application of oil, people strictly control the particle size of coal and dolomite. Should strictly control the particle size of bed material. Should be addressed furnace waste. To be able to solve the waste furnace after discharge. Natural gas boiler should be installed in areas where the application of calories, easy to install. Heating pipe can not be too long. It should have a good cable jacket. Water piping for an output from moderate to tail skew. Water resources to be equipped with a pressure regulating valve. As sewage gas, natural gas boiler chimney should widen to the outside, a heating furnace entrance width 1.5 to 2M. If you want to reduce the harm to the water wall tube can be appropriately regulate air pressure and wind speed and reasonable to reduce damage to the water wall. Inspection time is generally standby shutdown or shutdown condition. To check top head comprising the furnace wall is damaged, leakage of the furnace airtight and smoke. In the damaged condition requires immediate repair and welding, in order to ensure that no problem in the operation of steam boilers. Typically, before the ignition of gas-fired, fossil fuels must be added the charge in the combustion chamber, fossil energy and raw material-circulating bed material and gas in the wind, the strength and intensity of the flow down completely integrated. Bottom wind equipment, up for the core area. Exercise our powers in a ring outside the region along the furnace wall water swimming down, thus increasing the waiting time of coal particles in the furnace. Mineral particles, many of the ash and soot particles with a lot of fly ash, this resulting in rapid deterioration of the waterwall tubes continuously, so that damage to the wall thickness becomes soft, resulting in damage.
Subsequently, the Secretary-General Wang Jiao Ling line with the company's quality control staff had a discussion on the case of the reform of administrative licensing review of the existing boiler model in the country, how to promote the development of high quality assessment boiler, with the assessment of how businesses, trade associations and work promoting industry innovation and innovation to lead the development of what the expectations and demands, boiler regulations and technical specifications and implementation issues recommendations related issues exist in the process conducted in-depth exchanges and discussions, and Lu, president of the company's quality management staff made a lot of valuable Suggest. Wang Jiao Ling Secretary-General spoke highly of the technical aspects of the advantages of fast Boiler green energy and green development, and other fast-outstanding contributions boiler industry group to promote environmental protection and efficient process affirmed.
Boilers factors leading to incomplete combustion of boiler fuel used in modern industry, not only solved the problem of conventional boilers produced by environmental pollution, but also reduce the use of coal and other resources. But its combustion products, we sometimes found to contain a large amount of combustible material, and black ash, and combustion gas contains a lot of carbon monoxide combustible components. Such a phenomenon is a typical problem of incomplete combustion. Then the factors causing incomplete combustion of boiler fuel, what does? (1) a boiler furnace temperature enough below 600 ℃, good combustion can not be established in general structure. The amount of air (2) supplied in the fuel can not meet the need for complete combustion of the combustible component. The amount of air (3) of the boiler supplied sufficiently due to mixing a bad contact, the combustion disorder. (4) abnormal accident. (5) the fuel as received too much water, the moisture of more than 45% of the fuel is difficult to ensure the normal combustion boiler. (6) the fuel particles are too large, is not conducive to the combustion reaction. (7) The reaction time is insufficient combustion, boiler grate vibration amplitude is too large, the interval is too short, short burning time. (8) much ash, ash coke particles wrapping, slow combustion, (9) a feed lot, on the grate boiler fabric layer is too thick, not gas-solid benign mixed. (10) the feed grate or thin material less heat storage capacity is not strong. Incomplete combustion of fuel, not only a waste of fuel, while the impact performance of the boiler also to some extent, so we must note that when using these factors mentioned above.
