Sound policy is to ensure that important aspects of the mission of advancing the implementation of the transformation. On the one hand further increase financial subsidies. Coal-fired power boiler cleaning inspiring transformation, the Beijing Municipal Finance Bureau, the Environmental Protection Agency grant to improve the specification. 2002 drawn up "Beijing boiler subsidy fund management approach" rule, 20 tons of steam coal-fired steam boiler subsidy per ton 55,000 yuan, more than 20 tons of steam subsidies 100,000 yuan, on this basis, further increase this year big efforts to subsidize coal-fired boiler specification suburban counties agreed to 13 yuan per ton steam. On the other hand extends the fixed assets funded support plan. Beijing to carry out reform committee issued a "coal-fired boiler to adjust the cleaning power of fixed assets financed reconstruction municipal policy told the" arts boiler flow boiler 4 million to expand the coal-fired boiler cleaning power transformation of fixed assets to support planning, 20 steam tons of coal-fired boilers organization funded 30% share of grant funds in accordance with the original plan renovation projects. These policy measures to effectively promote the coal-fired boilers "coal gas" mission execution. Scale formation is extremely complex physical - chemical processes, the fundamental reason is due to the long-term use of the hardness of the water exceed state water quality standards caused. Also with oil boiler operating conditions, the boiler structure, design, installation unreasonable Arts boiler 8 million boiler processes, operations and low level of technology is also directly related factors. The main reason to build scale in the following areas: (1) due to the continuous evaporation of water in the pot, the pot constantly concentrated salts contained in water, when it reaches the saturation concentration of certain salts of calcium, magnesium and other arts boiler boiler 2.5 million process, and then continue evaporation, crystallization will produce precipitation, attached to the heating surface of boiler scale formation. (2) calcium due to water, heavy magnesium carbonate (i.e., temporary hardness) into the pot, decomposition at high temperatures, precipitation of soluble substance, the formation of scale adhering to the tube wall. (3) Because of certain salts of calcium, magnesium and other solubility decreases with increasing temperature Arts boiler feed water into the pot so that when the low temperature heat, temperature and precipitated. (4) Because of boiler blowdown unreasonable, not timely, non-adhesive nature, loose slag pot substances generated, a second-generation (or regenerate) scale, bonding in the boiler heating surface.
