hot water boiler malaysia price
The cross section of boiler hearth is generally square or rectangular. Fuel burns in the furnace to form flame and high-temperature flue gas, so the furnace wall around the furnace is composed of high-temperature resistant material and thermal insulation material. Water-cooled wall tubes are often installed on the inner surface of the furnace wall, which not only protects the furnace wall from burnout, but also absorbs a large amount of radiation heat from flame and high temperature flue gas.
The key to avoiding that the furnace excess air is reasonable air distribution and monitoring control means which adapts. Monitoring means are CO2 or O2 content measurement method for measuring oxygen gas boiler is usually carried out, because the combustion of gas boiler a slight positive pressure, the seal is easy to solve the problem, the oxygen content is measured more accurately reflect the excess air coefficient values. Oxygen measurement techniques now commonly used zirconia-type oxygen analyzer constant temperature, continuous on-line measurement of the oxygen content of the flue gas. The flue gas oxygen content as a reference, the correct air-fuel ratio adjustment, a low oxygen combustion.
Easy maintenance: There are movable smoke box doors in the front and back of the boiler, and there are observation holes and inspection holes in the rear of the boiler, which can be checked and cleaned up in the furnace. The manhole is set up on the furnace body, and the structural design takes the convenience of future repair and maintenance into full consideration.
Coal-fired boiler not only seriously polluted air, which produces a large amount of waste water sludge can also cause serious water pollution and soil contamination. To protect the city of Tongren green water blue sky, since 2014, led by the city of Tongren City, Guizhou Bureau of Quality Supervision, of 10 steam tons / hour within built-up areas and Tongren City High-tech Zone, Economic Development Zone, Tai Lung range and below, in Guizhou tobacco industry limited liability company Tongren cigarette factory, Tongren City, drug rehabilitation centers, Tongren Wantong construction and development Co., Ltd. and other 36 enterprises of coal-fired boilers to carry out an intensive diagnostic investigation. One by one on the ground to verify the registration, and the companies signed an undertaking to ban coal-fired boilers eliminated; to effectively reduce the burden on enterprises, according to the spirit of the document, to take the initiative within the time limit or eliminate the use of coal-fired boiler unit to switch to clean energy, the after review and acceptance Municipal Environmental Protection Bureau, according to the amount of coal-fired boilers hour evaporation reward, award criteria tons of steam per 30,000 yuan subsidy.
Up to now, the city of Tongren out of 36 coal-fired boiler units, a total of 43.051 tons of steam, an award subsidies 1,291,530 yuan, so far, the city of Tongren jurisdictions total phase-out of all coal-fired boilers, and lay a good foundation for the creation of ecological civilization demonstration area.
