coal project on boiler in hydralpower plant
As far as we understand fast coal project on boiler in hydralpower plant, Qinhuangdao City, Hebei Province to respond positively to tackling air pollution control actions, and intensive phase-out of coal-fired boilers. May 22, Qinhuangdao City Funing District launched the first action, a paper mill for a six tons of coal-fired steam boiler on-site demolition work. By Comrade Sun Guosheng, deputy director attended the action, and announced that coal-fired boiler central demolitions began.
Party Secretary Sun Zhichuan, Wang Hua district leaders to direct the demolition work, the Municipal Bureau of ecological environment, the ecological environment Branch area, technology and industrial Information Bureau, staying Town, elm Town, the next village management area, Funing town and other relevant units attended centralized demolition action.
The demolition operation was eliminated Qinhuangdao unified action to ban coal-fired boilers, Funing District is the city's main venue for the implementation of this action. 2019 coal-fired boilers area demolished 33 sets of objectives and tasks is that this concentrated action demolish 14 units, 12 sets of new coal-fired boiler investigation, a total of 26 sets of 248 tons of steam coal use is expected to reduce the amount of 149,444 tons, 145.73 tons of sulfur dioxide reduction , 439.37 tons of nitrogen oxides, soot 37.36 tons.
The fuel of 130 ton circulating fluidized bed coal project on boiler in hydralpower plant can be coal,gas,oil and biomass.with the development of the energy saving principle,there is no doubt that biomass is the most environmental friendly fuel for industry boiler.Compared with the traditional coal fired units, for the biomass power units, the emission of SO2 and NOx is greatly reduced, the PM2.5 content can be efficiently decreased in atmosphere and the local environment quality can be improved greatly.This is why the 130 ton biomass circulating fluidized bed boiler is one of the hot sale boilers in ZG company.
130 ton biomass circulating fluidized bed boiler adopts CFB technology map, saves the electricity cost and improves availability with all the advantages of strong adaptability for coal and low pollution emission.Therefore it is developed fast presently and it has get to be the most practical technology. The 130 ton biomass CFB boiler has made big breakthrough in low NOx combustion optimization control technology with many national patents.
Impact of vertical steam coal project on boiler in hydralpower plant efficiency is basically a bunch of the root causes of the country are carrying out high-profile coal to natural gas national movement, using the vertical steam boiler, very large cuts infected micro particles, toxic gases such as nitrogen oxides same time smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler. Combustion air is not sufficiently analyze the problem over the ratio: generally vertical steam boiler burner ejector, causing the air-fuel ratio can not maneuver scheduling. Lot of non-vertical steam boiler with automatic blower burner, leading to undesirable air-fuel ratio has the following several roots: air-fuel ratio does not contain points over about two cases: when oxygen is in excess, the excess cold air will have unlimited the effect of heat, resulting in increased operating costs vertical steam boiler, low vertical steam boiler efficiency; when oxygen is insufficient, will have insufficient incineration conditions, to produce low vertical steam boiler efficiency.
The heat exchange surface of Fangkuai coal project on boiler in hydralpower plant is reformed reasonably: 1. The horizontal boiler is removed from the furnace arch of the original furnace, and the coal bed is covered with insulation layer and refractory brick, which is transformed into the secondary radiation surface. Vertical boilers can build radiation reactors at the bottom of the furnace and install radiation arches on the upper part of the tank. 2, control the leakage air volume of furnace and flue. It is necessary to seal the boiler's observation hole, to seal the boiler's air duct and flue, especially when the air leakage rate of brick air duct and flue is large, after changing to burning gas, it is necessary to carry on the sealing treatment, preferably to change to the metal flue. When multiple boilers share a total flue, each boiler Breakers should be installed on the flue to prevent flue gas and residual gas from the purging process from flowing into the boiler furnace that has ceased to operate. Reasonable selection of burners for Fangkuai boilers: 1. Under rated gas supply pressure, the thermal load of the burners must meet the requirements of the boilers. Combustion is complete, excess air coefficient is low, combustion temperature is high, combustion noise is small, furnace flame fullness is good, flame radiation ability is strong. 2, the load regulation ratio meets the requirements of boiler operation, and the excess air coefficient can be adjusted. 3, can realize the boiler safety technical supervision regulations issued by the Ministry of Labor automatic control project.
