steam boiler for aac production line industrial oil gas
11.Steam exiting the high pressure steam turbine is called cold reheat.
It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.
Works chemical plant boilers is what works what chemical plant boiler is? Energy conversion device is a boiler, a boiler input energy comprises a chemical energy, electrical energy, thermal energy of the flue gas temperature and the like. After conversion of the boiler, steam, water or high-temperature organic heat carrier having a certain thermal energy to the boiler outlet. Mainly used in thermal power plants, ships, locomotives, industrial and mining enterprises. The main principle is a use of the chemical energy released by combustion of boiler fuel or industrial waste heat transferred to the water container, the water reaches the desired temperature or pressure of the steam heating apparatus. Boilers and boiler furnace two parts at the same time, water enters the boiler, the boiler heating surface in the steam - water system will absorb heat transferred to the water, so that by the hot water reaches a certain temperature and pressure to produce hot water or steam or, is introduced into the application. cation. In the combustion apparatus part, sustained release heat of fuel combustion, high temperature flue gas produced by combustion heat propagation, to transfer heat to the boiler heating surface, the temperature itself is gradually reduced and finally discharged through a chimney. Works chemical plant boilers is what - Classification steam boiler for aac production line industrial oil: First, the fuel can be divided into: 1, coal-fired boilers, 2, oil-fired boiler, 3, gas boiler, 4 electric boiler, boiler and nuclear 5, 6, waste heat boiler, etc., most top four, the most common, the lowest operating costs of coal-fired boilers, but a large area, serious environmental pollution, the requirements of operators, gas boilers high degree of automation, operating costs than coal, accounting small land area, requiring fewer operators, I did not use electric boiler, but running costs should be the highest, but the small boiler footprint, environmental protection is the best, the other boiler is not introduced, because I do not understand you the meaning of. two. The heat transfer mode can be divided into water-tube boilers, the thermocouple tube boiler, water tube boilers and fire tube boiler. Usually gas fuel boiler fire tube boiler, typical Type: series WNS (horizontal combustion boiler combustion chamber), this boiler characteristics: simple structure, the rated capacity of the evaporator is generally small (typically 10 tons or less, have a greater , but generally not more than 35 tonnes), starting the furnace pressure faster, lower quality requirements boiler; coal-fired boilers typically water boiler. Tube boiler, water tube boiler high thermal efficiency, but the complex structure of the boiler a higher quality requirements.
Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam boiler for aac production line industrial oil can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).
How to solve the air pollution problem caused by food processing boiler operation for a long time, coal-fired boiler boiler industry occupies 90% of coverage, coal prices are not high for the economy is relatively backward areas, as well as coal-fired boilers do not ask, you can use low heat, high ash low grade coal. But with the massive emissions of coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boiler problems faced overhaul or banned. Food processing industry as the foundation of human existence and life, in the face of more stringent food processing caused by boiler exhaust pollution treatment, clean type of fuel gas-fired boiler choice of various food companies. Take the gas boiler, it is generally used natural gas as a fuel, natural gas use since it was developed, it is known to clean energy. The main component of natural gas is methane (CH4), carbon dioxide generated during combustion only (CO2) and water (H2O), only when the combustion temperature is higher than 1300 ℃ when nitrogen oxides (NOx) and other substances, but to bring the processing operation of the boiler the air pollution problem, prefer to use natural gas as a boiler fuel. Fast boiler since its inception, and be fully independent R & D of gas boiler, condensing technology, research and development and use of FGR and premix combustion flue gas recirculation technology, greatly reduce emissions of nitrogen oxides (NOx) and other substances, NOx emissions may be less than 20mg / Nm³, our first-tier cities to meet the most stringent air pollution emission standards, compared with conventional coal-fired boilers, gas boilers party soon launch more environmentally friendly, can deliver good quality for the food processing industry steam.
