Harbin Ecological Environment Agency announced plans to complete this year, Harbin more than 65 tons of steam coal-fired china top boiler soot ultra-low emissions and transform 140 units, ultra-low emissions of sulfur dioxide coordination to complete the transformation of 51 units, ultra-low emissions of nitrogen oxide transformation 20. Currently, the transformation plan has been, is being gradually start building renovation project.

Harbin nine districts built-up area and more than 65 tons of steam coal-fired boilers totaling 156 units, according to the national, provincial requirements, before the end of 2020 to complete the transformation of ultra-low emission. By the end of 2018, it has completed the transformation of ultra-low emissions to 16, and the remaining 140 units planned to complete the 2020 pre-season heating. This year's program priorities ultra-low emissions of soot complete transformation of 140 units, ultra-low emissions of sulfur dioxide coordination to complete the transformation of 51 units, ultra-low emissions of nitrogen oxide transformation 20; completed 2020 pre-season heating boilers remaining sulfur dioxide, nitrogen oxide pollutants over low-emission transformation. Up to now, the district had been held property unit boiler promotion meeting, 28 companies have 140 boiler by one to clear a specific time frame for completion and responsible persons, are gradually start building renovation project, planned before the end of September to complete the transformation of building construction; the end of October front, complete run debugging; before the end of December to complete the project acceptance.

It is understood, Harbin source of ambient air particulate matter analysis result display, the largest contribution to the PM10 and PM2.5 pollution sources are fired, share ratio of 31% and 36%, respectively. Ultra-low emissions of coal-fired boilers is mainly transformation soot particulate matter reducing emissions to the atmosphere, thereby reducing the concentration PM2.5, effectively improve air quality.

2, Kai hot water china top boiler furnace operation

When Kai furnace again, should open the circulating pump, the water in the system to achieve the normal cycle, open the induced draft fan, blower, start the grate and the coal system, gradually recovered coal combustion. When the shutdown longer required pressure furnace, combustion should preferably seam, after clearing slag, then covered with a thick coal seam fire pressure.

Steam china top boiler works for example, everyone knows to pulverized coal, for example. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. 1. Works (in Example Pulverized) heat of combustion of pulverized coal in the furnace is first absorbed water wall heat transfer by radiation, evaporation of water boiling water wall into the large amount of steam for steam separator drum (excluding the DC furnace), the separated saturated steam enters the superheater, by radiation and convection absorbing roof, heat and smoke flue horizontal tail flue, the superheated steam to achieve the required operating temperature. Fired boilers are usually equipped reheater, to a high pressure steam heated cylinders. Reheat steam reheaters into the low-pressure cylinder continue to work to generate electricity. 2. pulverized coal work, the location of the center of the flame will affect evaporation. Generally, when the center of the flame is low, a large amount of evaporation, and when the high center of the flame, a small amount of evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Normally, when the center of the flame is low, superheated steam, in particular steam reheating temperature to be low, and the temperature of the superheated steam is high. 3. For the arrangement of the burner, the pulverized coal fired boiler on, there are front and rear walls thrust mode, quadrangular tangential combustion, dual mode combustion Tangentially more methods, each method has its own characteristics. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. It can not be applied because the same furnace arrangement above several simultaneously, the influence of steam can not be directly determined.

Such pressure hot water china top boiler will eliminate the ranks of the boiler. Therefore, the State Administration of Quality Supervision, Inspection and Quarantine issued the "Opinions on Several Issues implementation of Special Equipment Safety Supervision Regulations" (document number State Quality Inspection Act [2003] No. 206) which says: to develop a range of special equipment by the State Administration of Quality Supervision, State Council approved the "special equipment catalog" OK, the former State quality and Technical supervision issued by the "small and atmospheric pressure hot water boiler safety monitoring requirements" (State Administration of quality and Technical supervision order No. 11) involved in the pressure hot water boiler no longer part of the execution (details see "small and atmospheric pressure hot water boiler safety monitoring requirements" (State Administration of quality and Technical supervision order No. 11)).
