vertical flue d type boiler advantages
Pressure hot water vertical flue d type boiler advantages which features: Heating, hot water use can be achieved at any time with pressure hot water boiler, in order to improve the quality of life, people rush to buy value-pressure hot water boiler. When the cold weather to have a warm home environment; wash with hot water bath kept no longer kettle to boil water, these are the credit pressure hot water boiler.
Boiler excess air ratio is too low or too high, what harm? What causes high excess air ratio is? A: The vertical flue d type boiler advantages excess air ratio is one of the important characteristics of operational quality, the size value shows the degree of perfection combustion equipment and boiler operation. Excess air ratio is too low, incomplete combustion, increased flue gas of CO, the thermal efficiency is reduced; the excess air ratio is too high, the cold air does not participate in the combustion reaction in a large amount into the furnace, furnace temperature to drop, complete combustion. Also part of this excess of air also absorbs heat warming, and to take away the heat with the flue gas, reducing the thermal efficiency of the boiler. Therefore, a reasonable excess air ratio should not only ensure complete combustion of the fuel, but also can minimize the heat loss. Many cities now used in the boilers, a high excess air ratio, is because: (1) mechanical ventilation mismatches, to the excessive wind; (2) a furnace body, door, etc. leakage; (3) a flue, purification device air leakage.
Gas vertical flue d type boiler advantages key factors "denitration" in - Temperature: "denitrification" is a process of removing nitrogen oxides in the exhaust gas boiler flue gas in order to prevent increasing environmental pollution, the effective air emissions of air pollutants, "denitration" the words have been as a matter of public concern around the world.
This year, Harbin, Heilongjiang Province, the financial sector to actively promote the elimination of coal-fired vertical flue d type boiler advantagess, 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.
