Power 1 minute heater hot water circulating from the tank to the radiator outlet temperature is above seventy degrees, thirty minutes radiator temperature of more than seventy-five. Electric the modular commercial coal hot water boilers is the use of non-pressure plumbing circulatory system, a machine belt, not dry, is the development trend of modern boiler.

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.

Layer burning coal combustion boiler, the coal through the coal chain grate conveyor plane, the complete combustion process in the furnace. While the combustion gas boiler combustion chamber, the gas is mixed with air in advance is set in proportion to the burner, injected into the furnace through a nozzle, the torch was installed in the furnace to complete combustion. 2. Combustion of Coal mainly by c, H, s, 0, N, and other elements composed of ash and water, but not the mechanical mixing of these components, but a very complex compound. Coal combustion heat release, and smoke into the atmosphere by the SO²SO³NOx generated, environmental pollution, harm to humans the main component of natural gas is methane (CH.) Gas, and a small amount of non-hydrocarbon gases. Generally free of moisture and ash after the combustion of natural gas, produce mainly water co2 and emit a lot of heat, deleterious SO2, SO3Nox other emissions is relatively much less coal.

Boiler structure have? The whole structure, including boiler and boiler auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.
