April 17, Nantong, Jiangsu Province, the municipal government issued the "Nantong City 2019 air pollution control program of work" ( "Program"). "Plan" is mentioned: Nantong City, 153 Taiwan boiler regulation reform, which involves natural gas boilers, biomass boilers, coal-fired boilers; renovation project and will continue to implement ultra-low emission coal-fired units, a total of six thermal power companies more than 10 sets of 75 tons of steam / hour implementation of ultra-low emission coal-fired boilers.
1, the implementation of total coal consumption control. Strict control of the city's total coal consumption, focus more non-power industry scale industrial enterprises in coal consumption, ensure the completion of the province for cut coal task, the city's coal consumption in 2019 than in 2016 to reduce 2.46 million tons. Strictly implement the "Interim Measures for commercial coal quality management," restrictions on the marketing and use of ash ≥16%, sulfur ≥1% of bulk coal. A ban on new coal-fired heating boilers, and strictly control new coal-fired power projects along the Yangtze River in addition to the common back-pressure coal-fired units no new coal-fired power generation, heating project.
2, to promote the integration of thermoelectric project implementation. Coal-fired boiler with a takeover condition within a radius of 15 km of promoting heating above 300,000 kilowatts of large units and small cogeneration units shut down integration. Hoi Mei Ah thermoelectric Ltd. law shut down two coal-fired units totaling 27,000 kilowatts, the letter Qidong Taiwan 12,000 kilowatts coal-fired units.
3, to carry out comprehensive improvement of the boiler. Establish a list of the city's boiler management. Before the end of 2019, 35 tons of steam / h coal-fired boilers and total phase law or clean energy alternative embodiment, suitable in accordance with the electric power, gas and other appropriate gas the regulation principle; promote clean coal utilization, promote clean and efficient coal-fired boiler , 65 tons of steam / h coal-fired boiler and above all ultra-low emissions and complete energy transformation; promote the transformation of low-nitrogen gas boilers, in principle, after the transformation of nitrogen oxide emissions concentration up to 50 mg / m, and in accordance with the corresponding boiler safety requirements. Urban built-up area of ultra-low emission biomass boilers implement reform; the remaining boiler with all the special emission limit requirements. Boiler renovation project completed in 2019 153.
4, to further promote the ultra-low emission coal-fired thermoelectric renovation project. Ultra-low emission coal-fired units continue to implement reconstruction project for six thermoelectric companies 10 75 steam tons / hour and over the implementation of ultra-low emission coal-fired boilers transformation. (Municipal Bureau of ecological environment lead)
5, along actively embodiment desiccant fumes off white coal-fired units. Huaneng Power International, Inc. Nantong Power Plant, Jiangsu Nantong Power Generation Co., Ltd. Nantong Tianshenggang power generators and Nantong Acetate Fiber Co., Ltd., Nan Ya Plastics Co., Ltd. and other companies implement flue gas dehumidification off white works.
6, the implementation of pollution control industrial furnaces special action. City casting, iron alloy, metal smelting and regeneration, glass, ceramics, tiles, refractory materials, lime, waterproof materials, fertilizers, inorganic salts, calcium carbide, etc., according to the melting furnace, the melting furnace, sintering machine (furnace), baking ( calcined) burning furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace nine types of trades to carry out an intensive investigation. Closely integrated with the second census of pollution sources, establish a management inventory end of June 2019.
Small china manufacturer low pressure fired steam boiler Description: Small steam boiler refers to the amount of evaporation per unit time is small and low steam pressure steam boiler, steam boilers generally small volume refers to less than 30 micro-liters exemption steam boiler, the mechatronic device, host auxiliary integrated, easy to use, simple to install, simply connect the power, water and heat can, installation, use and technology supervision department supervision is not. Working principle: Its basic principle is: by an automatic control device, to ensure control liquid during operation or high, medium and low probe feedback control electrode opening of the pump, is closed, the amount of water the length of time the heating furnace; it is set by the pressure switch with the constant maximum output vapor pressure steam, the water level falling furnace, when in the low water level (mechanical), water level (electronic), automatic water pump, to the high level, the pump is stopped replenishment; At the same time, the electric tube furnace heating was continued, a steady stream to produce steam, the upper portion of the top panel or instantly display the steam pressure gauge pointer value, the whole process can be automatically displayed by the indicator. Product: Small steam boiler in accordance with the fuel can be divided into small electric steam boilers, small fuel steam boilers, steam boilers and other small gas; in accordance with the vertical structure can be divided into small steam boilers, horizontal steam boiler small, mostly single small steam boiler , double the return of the vertical structure, large steam boiler three-pass mostly horizontal structure
Improve the thermal efficiency of gas china manufacturer low pressure fired steam boiler steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
