Gas straw pellet burning boiler circulating pump installation should pay attention: gas boiler circulating pumps are important parts, mainly in the media pipeline to provide power. Circulation pump installation is very particular, has a small circulation pump option election malpractice, and circulation pump installation also has some stress, the following specific look at it.
Further, a high pressure steam straw pellet burning boiler required to provide high pressure steam up to 400 ℃, about 4 atm, the high requirements for the furnace, a high manufacturing process requirements.
I. Definitions rated steam pressure of the straw pellet burning boiler: rated steam pressure refers to steam at a steam temperature of the boiler thermal efficiency predetermined steam boiler, steam temperature, water temperature, and a nominal long-term continuous operation must ensure boiler superheater main valve at the outlet boiler pressure, which is indicated on the nameplate boiler pressure. For boiler without superheater, denoted by the saturation vapor pressure at the outlet of the main valve.
Battle to win the blue sky, is the major decisions and plans to make a big party in the nineteenth, and is for building a moderately prosperous society, to improve the quality of life of citizens and establish a beautiful China's development goals. To fully implement the nineteen spirit, promote the governance of air pollution intensity and improve the living quality of the environment, this year March 8, Zhengzhou Municipal Party Committee General Office, Zhengzhou Municipal People's Government Office issued the 2018 air pollution control program and the corresponding subsidy policy, the implementation of low-nitrogen gas straw pellet burning boiler retrofit demonstration project, as follows:
Before the end of September 2018, the city's more than 20 tons of steam (with), and the urban areas more than 4 tons of steam (with) the completion of gas-fired low-nitrogen transformation project demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out in accordance with the 40% investment in equipment;
Before the end of September 2018, the city's more than 4 tons of steam (with), and the urban areas more than 2 tons of steam (including) low nitrogen gas boiler reconstruction project completed demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out according to 30% of equipment investment;
Before the end of April 2019, the city completed all gas-fired low-nitrogen transformation, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, the municipal finances awards complement of 15% investment in equipment.
