company list of boiler manufacturing company in bangladesh
Use of natural gas company list of boiler manufacturing company in bangladesh, so what can energy-saving? Natural gas boiler. Effective heat value but its low calorific value of about 8500 kcal / cubic its high calorific value of up to 10,000 calories, the extra part in burning Nao process becomes superheated steam with the flue gas discharged out, the exhaust gas temperature can reach about 220 degrees to install a waste heat recovery tube in the flue gas outlet of the column, heated with hot flue gas is pumped into the preparation boiler water, you can save gas more than 5% ,, Thus, in terms of low calorific value of the thermal efficiency of the boiler can be 88% to 92% to 98% to 102% 1, to improve the conditions of the air flow encounters improved gas boiler gas and air two streams communicating condition, and an object thereof is to increase the contact area. The greater the contact area, the greater is the reaction area, strengthen the burning. Specific measures may be air and the gas stream into small strands, so that the two streams meet and intersect with a certain velocity; cell stream of gas (generally a gas) passes through and submerged in another stream of air, and the like. 2, enhance mixing, scrambling combustion gas boilers burning gaseous fuel is a single-phase reaction, ignition and combustion of solid fuels easily than, but the rate and extent of complete combustion is mixed with the combustion gas and air quality are closely related. Better mix, burn more rapidly and completely, the flame is short. Therefore, as long as the stability of the flame is not destroyed, it should enhance airflow velocity gas stream in the combustion chamber outlet or even a baffle at the inlet of a large resistance and the like obstacles, let hitting, red flame, increase turbulence in the airflow to strengthen the mix. 3, preheated air and gas to increase the temperature of gas and air, can be enhanced combustion reaction. It should therefore be preheated using waste heat of exhaust gas and air temperature, thereby increasing the combustion temperature and the flame propagation velocity of the combustion process to be strengthened. 4, rotation of the rotating stream and the recycle gas stream causes turbulence and mixing can be enhanced. Meanwhile, in the center of the rotation will form a reflux stream of large gas back area of the boot cycle, both to strengthen the mixing, also extended the flue gas flow path and residence time within the gas boiler and reduces loss of incomplete combustion. 5, flue gas recirculation in order to improve the combustion gas temperature of the reaction zone of the boiler, the flue gas may be directed to a portion of the high-temperature combustion data, so that the end of the fuel mixed with the burning or combustible mixture, in order to improve the combustion intensity. But take note that the amount of flue gas recirculation should not be too large, otherwise it will dilute the combustible mixture and the hook due to excessive inert substance, but slows down the combustion, pyrolysis and even anoxia, resulting in loss of incomplete combustion gas boiler.
Three common pressure hot water company list of boiler manufacturing company in bangladesh type on the market
Pressure hot water boiler is the more common type of boiler It also whether the title of hot water boiler pressure. This is because the top of the boiler is provided through the atmospheric port, using pressure to maintain a balance with the outside world, the boiler is not under pressure, there is no security risk and high-quality, durable, become the main equipment heating and hot water supply.
To improve the quality of atmospheric environment, the Xinjiang Uygur Autonomous Region issued a "Xinjiang Uygur Autonomous Region Air Pollution Prevention Act" (hereinafter referred to as the "Regulations"), adhere to all the people involved, the source of governance, planning ahead, treating the symptoms, cooperative control, damage to bear responsibility in principle.
First, governments at all levels should implement the total coal consumption control system, adopt economic and technical policies and measures to reduce the total coal consumption, encourage and support the development and utilization of clean energy, and guide enterprises to develop clean energy alternatives to reduce coal production , use of atmospheric pollutants, emissions during the conversion.
Second, the regional government development and reform departments shall, jointly with relevant departments, according to the needs of economic and social development and regional environmental resources carrying capacity and other conditions, the development of total coal consumption reduction targets and control programs. State, city (prefecture) and county (city, district) people's government development and reform departments shall, jointly with relevant departments, according to the planning and control total coal consumption reduction targets, total coal consumption in the region to develop control plans and their implementation.
Third, promote urban built-up areas, industrial parks centralized heating, use of cleaner fuels. Before central heating pipe network coverage area, prohibit new construction, renovation, expansion of coal-fired heating boilers, central heating pipe network coverage, has been built using coal-fired heating boilers should stop using the deadline. In areas not covered by the central heating to encourage the use of clean energy alternatives, to promote the use of environmentally friendly energy-saving boiler. When the deadline out of the city government does not comply with national and regional scale coal-fired boilers.
Fourth, according to the city government to improve the quality of atmospheric environment requirements, delineated and publish high-pollution fuel combustion zone ban, and gradually expand the scope of the ban on high-pollution fuel combustion zone. In the combustion zone ban, prohibit the sale, burning polluting fuels; prohibit new or expanded high-polluting fuel burning facilities. Have been completed, should switch to clean energy within the prescribed time limit.
Fifth, governments at all levels should strengthen civil bulk coal governance, prohibit the sale does not meet the civil standard of quality coal for coal, to encourage residents to burn with high-quality coal and clean coal, to promote energy saving stoves, and promote the development of alternative and clean energy in rural areas use. Encourage rural energy-saving housing.
Pharmaceutical heating company list of boiler manufacturing company in bangladesh steam is how the selection of modern pharmaceutical companies to produce an important source of power. Main steam as a heat transfer medium, are widely used in heating and heating. Chinese medicine and its preparation extraction, concentration, dissolution, drying, sterilization, disinfection, heating, humidification, etc. should be widely applied. 1. How to choose type of boiler meet the technical requirements of the pharmaceutical production process, is an important factor affecting the normal operation of the modern pharmaceutical companies. Pharmaceutical companies not only need to be heated in the production process, also need to provide heating for the air-conditioning equipment. Clean air-conditioning systems not only need heating in winter, but also to raise the temperature of the air conditioning units in the summer after cooling, cooling and dehumidification, temperature and humidity to ensure a clean area. Major pharmaceutical companies for use in process heating, sterilization, washing, in addition to air conditioning, refrigeration, heating and the like.
