output hot water boiler

What condensing boiler water scale hazardous due to the condensing boiler is located in a different region. There are differences in the water hardness. When high chloride content and sulfate in water, in the condensing boiler as the water will continue to evaporate, so that they go beyond the limits of its saturation concentration is precipitated, and the drum, adhering deposition of water wall, and gradually form hard , insoluble in water scale. Multi scale deposited within the drum and the heating surface of the water wall, causing great harm to the condensing boiler and its operation. The main harm is done to scale: (1) scale is a poor conductor, its thermal conductivity is 1/5 of steel, the scale will affect the heating surface thermal conductivity. The increased thermal resistance due to heat caused by fuel waste, reduce the thermal efficiency. (2) due to the poor thermal conductivity of scale, fuel combustion heat is not well transferred to the water by the metal surface, resulting in the metal heating surface temperature increases overheating, reducing the structural strength of metal, and causing the drum is deformed Wall table, drum kits, tube wall section is reduced, which can result in poor circulation can not even over the water and cause water wall tube burn accidents, severe cases can lead to burst pipes. (3) When people using a chemical or mechanical cleaning descaling, will cause corrosion of the metal of the inner wall injury or reduce the life of condensing boiler.

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.
