heating boilers in usa
Hebei province is the use of industrial heating boilers in usas, countless large and small boilers, air pollution caused by coal-fired boiler is one of the problems of governance in Hebei Province, and therefore become a major coal-fired boiler control of air pollution in Hebei Province direction. Coal-fired auxiliary boiler control work steadily, the Hebei provincial government to develop a "" comprehensive management of air pollution in Hebei provincial financial assistance fund management approach ", the boiler subsidy detailed as follows:
1, rural areas electricity instead of coal subsidies
The household equipment purchase and install (including line transformation indoor) 85% of investment subsidies, the maximum subsidy per household amount not more than 7400 yuan, the provincial and city and county respectively 50%, the rest borne by the users themselves.
Residents give electricity for heating 0.2 yuan / kwh subsidies, provincial, city and county average bear, the highest household electricity 10,000 kwh subsidies, subsidies and standards tentatively scheduled for three years.
2, substitution of gas for coal in rural areas subsidy standards
The household gas equipment purchase and install the 70% investment subsidies, the maximum subsidy per household amount not more than 2700 yuan. Provincial cities and counties and respectively 50%, the rest borne by the user.
Heating gas for customers who use 1 yuan / cubic meter of subsidy per household per year up to 1200 m3 gas subsidies, provincial, city and county average bear, subsidies and standards tentative three years.
Given the highest building in the village of pipelines family home investment subsidies of 4,000 yuan, 1000 yuan assume the provincial, city and county to bear 3,000.
3, coal-fired boiler subsidy governance standards
Subsidies for coal-fired boilers, eliminate subsidies, a separate ban demolition of 30,000 yuan / tons of steam, the implementation of clean energy transformation of 80,000 yuan / tons of steam.
4, thermal power shutting down out of subsidies
Provincial for shutting down the unit by 300 yuan / kilowatt award given up, have been included in the national "Thirteen Five." Plan for shutting down the unit, illegal construction unit, run-of-life choice except unit and power capacity index trading.
Boiler heating surface layout more rational development of technology developed from. With ample output, high thermal efficiency, reliable operation, energy saving and many other advantages, a more rational arrangement of the heated area. Li sixteen biomass heating boilers in usas heated area should be less than the pressure of saturated steam temperature corresponding to the rated pressure. Biomass boilers is often the first control pressure within the drum safety valve should stabilize production plant requirements or by pressure "Steam Boiler Safety Technology Supervision" provided at least once every school setting and inspection. Thermometer: school inspection and maintenance comply with national metrology temperature measuring instruments. After loading with the school should check at least once a year. Blowdown: discharge (see Section sewage) Normal operation: normal combustion conditions in the furnace can be a general increase in thickness of the fire bed flat seam necessary. Iron grate into the furnace should not burn down when the boiler load. Industrial sectors: thermal power plants, shipyards, petrochemical factories and other precision instruments, bio-engineering, boiler arranged baking and food industry together more other supply process steam; plants need to use hot water in place. Areas of life: steam sterilization Hotels steam laundry use, equipment, canteen, using steam homes; homes, schools, office buildings, hotels and other places in need of heating; hot water baths and other hotels. 1, the structural design, larger space compared to the traditional boiler furnace, while secondary air is arranged very reasonable, advantageous for the formation of fuel combustion products during combustion. 2, the horizontal type double drum junction.
Operation of a gas heating boilers in usa with the daily management of the boiler put into operation must meet the following conditions: 1, boiler passed the test. 2, the boiler has been registered on file, no use permits boiler must not be put into operation. 3, fireman trained personnel evaluation, obtain operating permits and operating the boiler to adapt. 4, it is necessary to measure the water treatment and water quality certified laboratory personnel. 5, a complete set of practical rules and regulations, including: 1) personal responsibility; 2) boiler operating procedures; 3) mobile inspection system 4) equipment maintenance system; 5) the shift system; 6) Water quality management systems; 7) clean system; 8) safety and security systems; (b) softened water boiler, water quality should be consistent with GB / T1576-2008 "industrial boiler water quality," the relevant requirements. (C) for preparing for the steam within the boiler steam pressure close to the operating pressure when, for the steam pot before the water level should not exceed the normal water level, combustion in the furnace before the steam supply should be stable. When the total steam supply steam valve slightly open, micro steam heating pipe, while the pipe line vent valve open, releasing the condensate, warm-time decided according to the pipe length, diameter, and temperature steam, generally less than 10 minutes. Note that the case of heating pipe should the pipe expansion and pipe stent, if there is no abnormal situation, stop heating pipes and eliminating faults and defects. Be heat-pipe, before full total steam valve, open when the condensed water should be carried out slowly pipeline is gradually reduced, while paying attention to whether the boiler has a special sound for each member, if any should be checked immediately. After total steam valve fully open, the total steam valve handwheel should be returned half, not prevent rotation of the thermal expansion. To prevent steam with water not allow in any case the water level exceeds a high-water mark on the glass.
Resulting in no water because the heating boilers in usa boiler is a special operating device, it is through energy conversion, the converted obtain steam, hot water, but it has transitioned easily occur no water phenomenon, gave the following tell you about the reason no water equipment: 1, the valve, the valve drum, Sheung Shui master valve in any stagnant water are a close. 2, on frozen water pipes or valves. 3, the drain valve is damaged or the drain valve is not fully closed. 4, the pressure to pump enough. 5, boiler feed water pump to the water supply pipeline rupture than pot. 6, the valve, the valve drum, the main valve of any one Sheung Sheung hose rupture or bad. 7, boiler leak. After boiler boiler conversion, output out steam, high temperature water or organic heat carrier has a certain energy, so that it no water problem is very serious, we must pay attention to it, ensure the normal operation.
