industrial wns gas steam boiler

"Henan 2018 campaign of air pollution control plan" recently introduced, to guide and encourage medium-sized coal-fired boilers eliminated. In the province's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers.

Financial awards complement the way:

1, the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

2, the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;

3, the completion of the coal-fired boiler Chaigai before the end of October 2020 no longer give financial awards complement.

Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.

Basics gas and steam oven basic principle as the principle gas industrial wns steam boiler and knowledge: steam as a heat carrier gas, forced circulation pump circulating the liquid phase, and then reheated to return, once-special industrial furnace. Widely used, such as petrochemicals, textiles, printing, plastics, rubber, food processing, wood processing, thermal asphalt, carton production, vegetable dehydration, drying, and other drying foundry sand. Gas steam boiler is an energy, security, heating equipment, is an ideal alternative to steam boiler products. The working principle is conveyed back to the respective thermal heating apparatus petroleum oil heater (endothermic) (organic heat), heat conduction through the (thermal energy release), and then returned to the furnace, formation of a closed circle in the process of compulsory to achieve the purpose of heating. Performance and features: 1, low temperature. As the temperature rises conductive oil, the viscosity of the system will continue to reduce resistance to decline, it will also reduce stress, more conducive to the safe operation and safe operation. Steam boiler is high pressure high temperature plume. 2, gas and steam heating system uses hot water inlet and outlet temperatures and equipment is 20-30 degrees, the closed forced circulation, heat recovery can be repeated, there is no waste, high thermal efficiency, energy-saving effect. 3, a low pressure gas and steam heating system, requires pressure equipment and the system will be reduced, and therefore, a simple production process of steam boilers, low investment costs. 4, the thermal efficiency can be maintained at optimal levels in various loads a level of 320 degrees and can adapt to the production requirements of the following types of thermal load, and temperature control can be precisely adjusted. 5, heating furnace to increase two to three times the temperature cycle can provide a wide range of processes, a variety of equipment to meet the different temperatures greatly reduces the need for investment in equipment.

Gas-fired industrial wns steam boilers and coal-fired steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas and coal-fired steam boiler steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answers to the same model or coal-fired steam boiler energy saving compared to steam boilers, we can roughly be calculated next-ton per hour boiler work at full capacity to 150-160Kg according to the market value of coal fuel, and gas to around 80m3 of gas. A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.

Main contents of boiler energy efficiency test:

1. Boiler thermal efficiency test: a) determination of boiler evaporation; b) boiler excess air coefficient detection; c) exhaust smoke temperature detection; d) fuel combustion efficiency test; e) boiler thermal efficiency test; f) fuel consumption; g) Steam to coal ratio.

2. Boiler new product stereotyped energy efficiency test: Determine whether the boiler thermal performance indicators are consistent with the design and determine the operation mode of the equipment. Such as boiler evaporation, boiler thermal efficiency, combustion efficiency, various heat losses and so on.

3. Boiler operation adjustment test: Determine the most economical operation mode of the boiler and identify defects in the boiler operation. Such as boiler maximum load, boiler minimum load, fuel requirements, economic load, reasonable exhaust gas temperature, optimum wind coal ratio, excess air ratio, secondary air ratio and so on.

4. Comparative test of thermal performance before and after boiler reform: changes in evaporation, effects of combustion, thermal efficiency of boilers, etc.

5, fuel industry analysis, elemental analysis: to judge the quality of oil, gas and other fuels, easy for enterprises to control the quality of fuel into the plant.

6, water quality testing, scale analysis: determine the quality of water, control the boiler water indicators to prevent boiler fouling.
