astm sa192 boiler seamless steel pipe factory
There are many types of heat load units for astm sa192 boiler seamless steel pipe factorys, four of which are commonly used, including large (Kcal), tons of evaporation (t), watts (w), kilowatts (kw). Large kcal (Kcal), also known as kilocalorie, 1 kilocalorie of heat equal to 1 kilogram of water temperature 1 ℃ increase in the need for heat.
To reduce the total coal consumption, reduce air pollutant emissions, Guigang Municipal People's Government announced the latest "2019 Guigang tackling air pollution control plan" proposed scheme: Guigang City is actively taking measures to reduce coal comprehensive use of renewable energy , natural gas, electricity and other energy alternatives to coal consumption, reduce the proportion of coal consumption, focusing on reducing the total non-electric coal consumption. New coal projects to implement alternative coal reduction, the implementation of inventory management, so that statistics can be verified.
Details are as follows.
First, the implementation of the total coal consumption control. Take measures to reduce overall coal, renewable energy, natural gas, electricity and other energy alternatives to coal consumption, reduce the proportion of coal consumption, focusing on reducing the total non-electric coal consumption. New coal projects to implement alternative coal reduction, the implementation of inventory management, so that statistics can be verified. October 2018 in conjunction with the regional government Council issued the "Guangxi county industrial park planning and adjustment plan" and other industrial park planning and implementation of the adjustment, the promotion of industrial parks to carry out "an area a heat source" upgrade, encourage 300,000 kilowatts or more coal-fired heating unit carried out the transformation in cogeneration planning guidance to promote the backward small coal-fired and coal-fired thermoelectric heat within the range of (biomass) integrated boiler shut down.
Second, accelerate the comprehensive improvement of backward small boilers. According to the State Administration of Work Market and three ministries "on the strengthening of energy-saving environmental protection boiler" (National City Supervisor ad hoc  No. 227) requirements to promote energy efficient boiler environmental protection, energy-saving environmental protection to promote the transformation of boilers, eliminate backward boiler. Coal-fired boilers built-up area to carry out an intensive investigation, the investigation out of the coal-fired boilers to register one by one, to establish accounting and inventory management, according to local conditions, Take Measures to develop small boiler (10 tons of steam per hour and below) Integrated remediation plan, the classification proposed remediation requirements, before the end of May 2019, the Municipal environmental Protection Bureau for the record. Carry out a comprehensive district built 10 tons of steam per hour and small coal-fired boilers out of work, according to the law to increase efforts to eliminate small coal-fired boilers in accordance with regulations, in 2019 the completion of small coal-fired boilers out of the task; all kinds of more than 10 tons of steam coal boiler strengthen environmental law enforcement supervision, strict implementation of emission standards for boilers that can not be stable discharge standards, shall order rectification according to law, after rectification still do not meet the requirements, shall not continue to use; to strengthen environmental law enforcement supervision of biomass boilers, in particular to strengthen regulatory biomass boiler ban on high-pollution fuel combustion zone of the city; biomass boilers boiler should be dedicated, efficient dust bags and other supporting facilities, prohibit blended with other fuels such as coal. The city and county-level cities above the built-up area in principle, to create a new 35 tons of steam per hour of coal-fired boilers and other regions in principle no longer new 10 tons of steam per hour and below the coal-fired boilers.
Check items Notes steam astm sa192 boiler seamless steel pipe factory and a steam boiler inspection Annex 1, the steam boiler pressure gauges, they check whether the abnormal water table, bend, and the intermediate connecting pipe mounting valve opening and closing without exception. The table below shows the water level is correct, whether the water table column drain valve correctly state, pressure gauge whether there is a statutory inspection mark within the time limit. 2, steam boiler safety valve, drain valve, vent pipe to check whether they have been adjusted to a predetermined opening pressure, vent pipe installation is reasonable. Check the vent pipe is blocked, whether the anti-Chen measures. 3, the opening and closing of the drain valve discharge inspection device is flexible, the gland liner whether to allow sufficient room for adjustment. Outfall road if there is an abnormality. 4, the main valve, the water supply shut-off valve and non-return check tie their open and closed states without exception, if the valve cover material left margin. 5, the air valve in the hydrostatic test water to full state, the start point of the furnace to appear vapor must be kept open state. 6, connection pipe inspection gas and water pipes, the support, the telescopic joint, and whether the hydrophobic insulation and meet the requirements. After scaling will overheat the metal, the metal will stretch creep, modifications, bulge, serious overheating of the tube when the storm. Scale layer is a heat medium and the metal wall; between the water vapor, since the scale layer is small thermal conductivity, a significant insulating effect, greatly increasing the temperature of the metal wall fouling. It is estimated that the evaporation heating surface, furnace deposited scale often overheated collapse, deposition of scale by the pot shell (drum) regular hot drum kit, the heating surface tubes deposition of scale is often overheat storm tube larger fuel amount of waste. Daily work to do steam boiler inspection matters, in order to ensure normal production.
Fluidized bed combustion (FBC) technology has been widely used in China for heat and power generation since the early 1960s due to its wide fuel flexibility, excellent emission control and wide range of load adjustability. In the late 1980s, this technology is developed into circulating fluidized bed combustion due to its advantage in scaling up and higher efficiency. Nowadays, the total number of FBC astm sa192 boiler seamless steel pipe factorys put into operation in China is about 4000, and about 3,000 of them are CFB ones.
