1 ton steam boiler steam generator steam generator Ji'an price

Currently, research boiler flue gas heat recovery is a fashionable topic. Boiler flue gas heat loss is the heat loss from the boiler largest one, the exhaust gas temperature increase of 20 ℃, the boiler would lose about 1% thermal efficiency. Installation of flue gas heat exchanger in the boiler flue gas after the air preheater to reduce heat losses the boiler is the main purpose of this system of the program. 1 installation of flue gas waste heat recovery project conceived paper Zhundong Region 2 × 350 MW Unit Project as an example, the use of flue gas heat recovery unit is a flue gas - water heat exchangers, boiler exhaust tail heat heating soda, related systems as envisaged. 1.1 determine flue gas systems engineering program, taking into account factors that operational safety and operational costs, etc., combined with engineering characteristics determine the flue gas system uses low dust area induced draft fan arrangement. 1.2 flue gas heat recovery heat medium grade determined for 350 MW units, the proposed flue gas heat heating condensate systems, the condensate into the system in order to improve the initial temperature. The main thermodynamic system runs as follows: the unit normal opening process, the flue gas heat exchanger inlet and outlet valves open, the water side of the heat exchanger is a closed loop system, condensate flue gas heat exchanger to absorb the water side of the heat exchanger flue gas heat, heated to a certain temperature into the turbine side of the condensate system and heating continued. Taiwan added to the water system expansion tank and regulator for balancing the water cycle, water from the chemical water treatment room. 1, fuel gas-fired boiler during operation Note the following points: (1) does not allow pressurized combustion or furnace smoke. (2) Fuel gas-fired boiler at the bottom of the plane can not land on the water, to prevent moisture corrosion. 2, the boiler runs every 2-3 weeks, should be checked again. 3, boiler every 3-6 months, should conduct a comprehensive inspection and maintenance shutdown. (1) internal and external boiler inspection, such as compression weld parts, steel inside and outside for corrosion phenomenon, if found serious flaws should be repaired, if the defect is not serious until the next time also repair shutdown, if there is suspicious, but does not affect safety during production, should be made to record for future reference. (2) checked the water in the boiler primer coating to prevent corrosion. 4, boilers and boiler base paint at least once a year. 5, the fuel gas boiler often of unused Maintenance: dry and wet two kinds of shutdown more than a month, should be taken care of dry method, the following can be wet month maintenance shutdown method. LSS is a vertical-type oil or gas boiler combustion bent water tube boilers. Biasing structure using curved pipes, high temperature discharged from the burner flame first scour furnace smoke pipe, and then enter the rotation after the second return from the smoke chamber consisting of curved pipes, www.zhengqifashengqi.com through the chimney into the atmosphere. Boiler equipped with a removable mosaic structure, the boiler maintenance is very convenient. Boilers with good technical performance burners, combustion using automatic ratio adjustment, feedwater automatic control, program start and stop, automatic operation and other advanced technologies, and has low water level alarm and low water level, high steam pressure, turn off automatic protection function . The boiler has a compact, safe, reliable, simple, quick to install, less pollution, low noise, high efficiency. Whether domestic or imported steam boiler steam boiler, steam boiler outlet steam pressure if in accordance with division of words are the following categories. Low pressure boiler, pressure boiler, high pressure boilers, boiler subcritical, supercritical and ultra-supercritical boiler boiler. The main power plant boiler system devices generally include: body equipment, combustion equipment and auxiliary equipment. Wherein the boiler equipment consists of: two pot and stove parts. Where: pot by the drum, down pipe, water wall, superheater, reheater, economizer and its connecting piping soda system. Furnace from the furnace (steel), burners, flue, preheater and so on. There need to import steam boiler, then you can consult.
