Hefei is the blue sky to win the Battle of key areas for innovation to create an international influence is of great significance. Is determined to win the battle of the blue sky, the city combined with the actual situation, formulate a three-year action plan to win the embodiment Battle of blue sky. Details are as follows.
I. Target: 2020, sulfur dioxide, total nitrogen oxide emissions were reduced over 23.1% in 2015, more than 24.2%; PM2.5 concentration decreased more than 18% in 2015, the ratio of the number of days air quality assessment requirements up to the national , severe pollution and over several days ratio decreased by more than 25% compared with 2015; the full realization of "thirteen five" binding targets.
Second, the continued implementation of the total coal consumption control. By 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's total coal consumption to complete the tasks assigned by the national and provincial; new coal projects to implement the reduction of coal instead.
The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement may be within the total national and provincial construction plan developed according to the control range, co-ordinate arrangements for the construction of ultra-low emission coal-fired capacity unit.
Third, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, ceramic, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry characteristics can actively promote industrial production, building heating and cooling, transportation, agricultural production, the implementation of the residents living in five major areas "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for. Of the new "coal to gas" projects, we should adhere to increase coal gas reduction to gas will change under the premise signed gas supply contracts, orderly implementation.
Fourth, to carry out comprehensive improvement of coal-fired boilers, coal-fired boilers to increase efforts to eliminate, consolidate the results of coal-fired boilers eliminated. Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation, one by one registration. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour and coal-fired boiler above (except boilers fired power plant) all meet special requirements emission limits; allowed to remain 65 tons of steam per hour coal-fired boiler and above all the complete energy transformation and ultra-low emissions within the city. County (city) district, zone one by one before the end of June 2019 to develop low-nitrogen combustion rehabilitation programs for existing gas boiler, complete combustion of low nitrogen transformation in this area of existing gas boiler before the end of 2019 more than 50%, before the end of 2020 transformation is substantially complete; after transformation principle NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. Urban built-up area of ultra-low emission biomass boilers implement reform.
The outlet temperature of the hot water professional firetube boiler should be lower than the corresponding saturation temperature at the operating pressure (ie, the vaporization temperature of the boiler water) below 20 °C.
Water tube boiler in Honduras with 120 ton
Hot water professional firetube boiler described configuration (1) a substantial increase in the furnace inlet and outlet temperature, sound and light alarm overheating. (2) furnace and piping outgoing rhythmic percussion, pipe vibration. (3) furnace barometer hands shaking, the water pressure increases. (4) output vapor valves, Peng Zhang steam box. Followed by hot water boiler sake vaporized boiler water (1) a sudden termination of the pump power limit, a final break through the bad, or no effective countermeasure failure, leading to gasification. (2) furnace employees not yet Workout Do not use hot water boiler. Such as coal Stop, stop exhaust, induction stop, stop the pump mistakenly stopped, hot water boiler ignition, after the first ignition open; when shutdown, the pump stops after the first reduction furnace and so on. (3) due to not turn off the circuit through the bad incorrect valve entrance, gate or frozen cleaning conduit, dirt or the like clogging terminated. (4) hot water boiler or through a bad circuit leaks, invalid constant pressure equipment, not immediately moisturizing, resulting in water flow and pressure drop is not enough. (5) hot water boiler entrance thermometer, barometer ineffective, not processed in the furnace tube. (6) Zongtisheji scientific furnace, boiler or furnace into hot water by a steam boiler, a heating furnace so that flow rate is extremely well-balanced, part of the water heating surface due to slow gasification. (7) severe internal outfall stains or debris destroyed the water cycle. Hot water boiler pot of water vaporized solution: (1) rapid decrease lit, reduce the oven temperature. (2) when the limit power, back-up power to be coupled, or the reserved start of the circulation pump by the engine controller. (3) No back-up power and his response, the entrance and the return valve to be switched off, drinking water supply must furnace, and the furnace inlet and outlet drain valve to be open drain, the water can swim and furnace cooling heating surface, until the heat storage furnace has been cleared. When no drinking water or drinking water can not be sure that, decency backwater bypass pipe may be introduced to the furnace, then by a valve to exclude the cooling furnace heating surface. (D) Security Council notes furnace destruction, should replace them immediately. (5) When the furnace temperature increased significantly, gasification serious, should an emergency turn off the stove. About hot water boiler is vaporized sake and solutions.
