Gas steam boiler operating principle: a steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporize into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source.
Boiler in concept and requirements if there are unknown? In knowledge and learning to master the boiler, the following will be specifically related to their work, but also is something new for everyone by learning to make their own progress in their learning on the road, so you can make yourself benefited shallow, and there will be harvest. 1. condensing gas boiler in the boiler, what is its core technology? Condensing the gas boilers, their use of technology, and technology for condensing the two non-combustion technology. In the condensation technology, the main advantage is the ability to reduce heat loss caused by the combustion of fuel, to thermal energy absorption efficiency, thereby reducing emissions of harmful substances and produce, to avoid environmental pollution. And smokeless combustion technology, it is possible to reduce the emissions of nitrogen oxides, prevent acid rain and the greenhouse effect. 2. The high-pressure boiler tube boilers, the specific requirements? Boiler, high pressure boiler tube which it is used, on the properties, belonging to a seamless steel pipe. Therefore, in the manufacturing method, it is consistent with the seamless steel tube, but its steel requirements are very strict, because it is by its working environment in which to decide. General, is required to have high strength, and good resistance to oxidation and corrosion rust performance. And, can also durable.
How to choose the heating boiler and hot water boilers for chile load calculation: the boiler, which related to the difficult problems it has? These issues should be how to answer? Raised these two issues is to elicit the article content, and at the same time, so that we can also have learning objectives, so in order to learn something, and to ensure the quality and effectiveness of learning, in turn, may be the site of this important product for the boiler, further knowledge and understanding. 1. civilian small boilers installed, which is typically why the boiler? Civil mounted small boilers, which is generally a normal pressure boiler, rather than other types of boiler, so at this point, there should be a correct understanding, can not go wrong. Further, on the way the system that there are two, one is natural circulation system, the other is a forced circulation system, implemented by the pump. 2. In the heating on, how to select and determine the boiler? On heating, the boiler is selected and determined, the area is known to some specific aspects, such as room heating, the room toward the wall insulation, roof structure, and these indoor and outdoor temperature and the like. Also, determine the appropriate amount of heating sheets, and the length of the heating pipes. Through these into account, to get accurate results.
This year, Harbin, Heilongjiang Province, the financial sector to actively promote the elimination of coal-fired boilers, 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.Free Chat
