Hot water boiler in South Africa can be divide into oil fired hot water boiler, biomass fired hot water boiler, coal fired hot water boiler, gas fired hot water etc, according to different fuels.
Currently, biomass boilers results in incomplete combustion of the fuel in the main factors: the temperature of the furnace is not enough, lower than 600 ℃, good combustion can not be established normally structure; the amount of air supplied to the fuel can not meet the combustible components required for complete combustion; amount of air supplied is sufficient, but due to the mixing and contacting do not, initiate combustion disorder; water-based fuel used in the boiler is too large, when the fuel moisture more than 45%, combustion can be difficult to ensure normal combustion; fuel particles are too large, is not conducive to combustion reaction; or the reaction time of the combustion grate enough vibration amplitude is too large, the interval is too short, insufficient burning time; much ash, coke particles and wrapped, the combustion rate slowing; feed lot, on the grate fabric layer is too thick, gas-solid mixture is not benign; feed grate or thin material less heat storage capacity is insufficient. Products of biomass combustion boiler, contains a lot of combustible, ash black, sometimes visible raw material is discharged. The combustion gas contains a large amount of carbon monoxide combustible components. Factors causing incomplete combustion boiler fuel as follows: (1) the furnace temperature is not enough, lower than 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) is sufficiently supplied, since poor mixing and contacting the combustion disorder. (4) abnormal accident. (5) too much water the fuel as received, more than 45% of the water is difficult to ensure the normal combustion of the fuel. (6) the fuel particles are too large, is not conducive to the combustion reaction. (7) the reaction time of the combustion is insufficient, the amplitude of vibration of the grate 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 fabric layer is too thick, not gas-solid benign mixed. (10) the feed grate or thin material less heat storage capacity is not strong.
The 7-ton wood chip biomass boiler is a common application in hotels, food processing plants, wood processing plants, and wood is a very common biomass fuel, but it is not suitable for direct use in boilers. In general, biomass such as wood needs to be processed into granules for better utilization. Wood biomass boilers mainly use wood pellets as fuel to generate steam or hot water for various purposes.
Second Session of the CPPCC National Committee Session of March 5 press conference held in the afternoon, the CPPCC National Committee of Population, Resources and Environment Committee, Democratic National Construction Association Central Committee, Environmental Management Division of the Ministry of Ecology Environment Atmospheric Liu Bingjiang said: Last year, resolve more than 30 million tons of steel production capacity, 810 million kilowatts of coal-fired units basically reached the national emission levels of natural gas, built the world's largest clean coal power base, out of 1.3 million units in industrial furnaces, coal accounts for the country's primary energy consumption the proportion of first time below the 60% to 59%, and turned off the small coal-fired boilers 23000 units.
At present the country has completed a preliminary air pollution control goals, the future will continue to promote coal-fired boilers governance, and the introduction of more stringent emission performance standards of air pollution.
