This year, Harbin, Heilongjiang Province, the financial sector to actively promote the elimination of coal-fired boiler blowdown heat recovery systems, and adjust the phase out coal-fired boilers financial subsidies, currently co-financing of 291 million yuan to support the city's coal-fired boilers out of work.

Combined with the characteristics of this year's work out coal-fired boilers Harbin, Harbin Finance Bureau jointly relevant departments to improve the policy adjustment, will expand the scope of the grant to build outside the area 10-20 tons of steam coal-fired boilers built-up areas and 10 tons of steam and less fuel coal boiler. Meanwhile, according to the actual situation of Harbin clean energy alternative work policies to increase financial assistance "from coal to biomass" approach; and to develop a more favorable subsidy policy of clean energy transformation of the urban fringe, the energy-saving house into the scope of the grant.

It is reported that, according to the above subsidy policy, the current urban levels, the financial capital of 291 million yuan has been implemented, which has been ahead of municipal finance district grant funds allocated 159 million yuan, 132 million yuan of the burden of the district also implemented through subsidies for local government bonds ways , effectively protecting the city out of coal-fired boilers work smoothly, since the Harbin into the winter heating period, ranked in the top 20 of 169 major cities in air quality rankings.

Must not dry gas steam boiler blowdown heat recovery system or water during operation of combustion: fuel gas steam boiler combustion may not be anhydrous or water during operation, then the boiler may be in the dry state. When a user finds a boiler in such a situation, the user should be vigilant, timely and secure processing, in order to make the boiler to avoid irreversible serious accident.

Why do you want to use softened water boiler blowdown heat recovery system in everyday life, we often see after the inner wall of the kettle with a long time scale will be generated. This is what causes it? We had access to the water contains a lot of inorganic substances such as calcium, magnesium and so on. These salts can not be visually found in water at room temperature, they are once heated to boil, there are a lot of calcium, magnesium carbonate precipitated form, which is formed close to the pot wall scale. We usually water calcium and magnesium ions with the content of the "hardness" is represented by an index. Hardness equivalent to 1 liter of water containing 10 mg of calcium oxide. Less than 8 degrees is called soft water, hard water is higher than 17 degrees is called, called hard moderate between 8 to 17 degrees. Rain, snow, river, lake water is soft water, spring water, deep well water, the water is hard water. Water softener has the following effects: (1) to prevent water pipes, water heaters, coffee machines, humidifiers, steam irons, bathtub, shower heads, toilet and other household appliances accumulates scale, often blocked, and low thermal efficiency of the phenomenon. (2) coffee, red tea, unique taste, pure taste. Gardening, to extend the flowering period, green leaves no spots, bright flowers. Fish, all kinds of fish disease prevention. Soft water to cook full, fluffy and good taste; sanitary ware, crystal clear, no stains spots. (3) prolong the shelf life of tofu, soy milk more fragrant, bean sprouts without auxin, growing thick. Vegetables, remove agricultural chemicals, to extend the shelf life of vegetables. Cooking, to shorten the time, smooth soft rice, pasta easy expansion. Cooking, keep the natural taste of vegetables and nutrients. (4) inhibit fungi, promoting trauma healing, reduce constipation, gastrointestinal incidence risk category of stones diseases. Occurrence of skin trauma, frostbite, burns and the like when the accident, after the first use soft water wash the affected area, and to soft water wet cotton, gauze, a towel, graze the affected area, rapid healing, and the edema due to burns immediately disappear, this is due to the soft water has the effect of promoting tissue regeneration. Fungi can inhibit the regeneration of cells and tissues. Occurrence of skin trauma, frostbite, burns and the like when the accident, washed with soft fast healing. (5) washing to prevent static electricity, bleaching, variant, washing dishes, clean and without water, to improve the gloss vessel. Cleaning the kitchen bathroom, strong decontamination and deodorization. It has strong detergency. Soft water washing clothing fibers, not stiff, brittle, saving detergent. (6) soft water virtually eliminating water base, the safe operation of equipment, saving expenditure, reduce water equipment and water pipe repair costs more than 60%, reduce fuel costs more than 30% of the hot water, detergent to reduce purchase costs more than 50% .
