The large-diameter cylindrical water storage boiler shell vertical energy saving, the appearance of fine, automated process, excellent service. Biomass boiler volume must be born on the 18 th century, the British steam engine boiler coal use substances, including J. Watt, including early steam engine, the steam pressure used is equal to the atmospheric pressure. After the second half of the 18th century above atmospheric pressure instead of steam. Early steam boiler is a boiler fuel biomass boilers of the 19th century, the commonly used steam pressure increased to about 0.8 MPa. Boiler with this adaptation, early steam boiler is filled with water to a large diameter cylindrical vertical potshell, then switch to a horizontal boiler shell, a fire is burning furnace brick shell below the pot. With bigger and bigger boiler, installed in the fire tube boiler shell, the front end light a fire in the fire tube, the flue gas from the back of the fire tube, the exhaust chimney and the external heating by the boiler shell brick flue, known as fire tube boiler. Cylinder means only starts a fire, a fire tube boiler or called single boiler Connie Hsu; was applied to two fire extinguishers, fire tube boilers or called double Lancashire boiler.

2, high-pollution fuel combustion zone ban prohibits the sale, burning polluting fuels; prohibit new or expanded high-polluting fuel burning facilities; has been completed, should stop using within the prescribed period the Municipal People's Government, or switching to natural gas , liquefied petroleum gas, electricity and other clean energy.
4, petrochemical enterprises should strengthen the recovery of combustible gases. Flaring device should be used to deal with emergencies, not as a daily air pollution treatment facilities.
5, to encourage the production, use, or free of volatile organic compounds less volatile organic content of the feedstock and products. Surface coating, packaging, printing, furniture manufacturing and other industries should use low VOC content of products. Petrochemical and other organic solvent, the company should improve the production process, a low content of volatile organic materials and products.
6, resulting in production and business activities of volatile organic waste gas should be carried out in a confined space or equipment, and the installation of, use of pollution control facilities. Shipbuilding and other production and business activities can not be carried out in a confined space, and building (structure) building routine maintenance of live animals, roads, bridges, etc., should take effective measures to reduce emissions of volatile organic compounds.
Is selected from the steam 3640kw electric steam generator heating gas boiler hot water boiler according to the output medium to distinguish, it can be divided into hot water boiler, a steam boiler. In daily life, many industries will be used in heating boilers, conventional heating, steam boilers and gas heating boilers can meet the basic requirements, but now using a hot water boiler. ? So in the end the election heating steam boiler or hot water boiler with a steam heating boilers, heat exchangers use more intermediaries do, in fact, reach the user's media is still hot, steam heating but has several disadvantages: 1, heating up too fast, heat is cold and hot temperatures, easy to leak. 2, the booster fast, easy to cause a heat sink metal fatigue life reduction, are likely to cause the radiator burst. 3, the water in the boiler heating fuel absorbs heat released, and the water molecules have to absorb some heat into steam, causing energy waste. Therefore, the use of heating hot water boilers for more energy-efficient than steam boiler, so one after another in recent years, some local steam boiler heating system to heat hot water boiler, steam boiler when the heat source is less and less, even extinct. But there are many like hospitals, hotels and other places need both steam and hot water needs, then choose steam boiler or hot water boiler is necessary to have specific analysis: If the hot water heating system using a large amount of steam required is very small, it is recommended another arranged outside the small hot water boiler steam boiler or steam generator in order to meet the needs of a small amount of steam. Because based on actual experience, in addition to a steam boiler efficiency problem in itself a significant attenuation in the low load operation outside the state, the greater the loss of energy consumption, energy efficiency is generally only about 60%, serious waste of energy. Overall, commercial premises heating systems, gas hot water boiler to be more significant than the energy-saving advantages of steam boilers.
Description electric heating 3640kw electric steam generator electric heating boiler convert electrical energy into thermal energy, the pressure of the water is heated to hot water or steam (saturated steam) a thermal device. It requires no furnace, flues and chimneys, and without the fuel storage site, greatly reducing the pollution caused by conventional coal-fired boilers. Electric boiler with no pollution, no noise, small footprint, easy to install, fully automatic, safe and reliable, the thermal efficiency of 98% or more other features, is a green product. Many countries in the late 1970s to the early 1980s, began to research and development of electric boiler. China in the mid-1980s, started developing electric boiler products, by the mid-1990s, many companies will be applied to electric heating boiler, central air conditioning and hot water supply. Category: Electric heating boilers are divided into three categories: LDR (WDR) electric steam boilers, CLDZ (CWDZ) electric hot water boilers and KS-D electric water boiler. Electric water boiler which is divided into KS-D electric water boilers and XKS-D electric storage water boiler. The impact of fuel: in the development process of the boiler, the type of fuel has a great influence on the furnace and combustion equipment. Therefore, not only requires development of various combustion furnaces to adapt to the characteristics of different fuels, but also to improve combustion efficiency to save energy. Additionally, technical improvements of the furnace and the combustion device further required to minimize contaminants (sulfur oxides and nitrogen oxides) in an exhaust gas boiler, coal and wood early shell boiler fixed grate, and multi-quality coal burning wood, coal and slag are added by hand. It began to grate after mechanized straight water tube boilers appears, chain grate has been widely used. Blowing wind never segmented cartridge system under development into segments blowing grate. Early furnace low, low combustion efficiency. Later, it was recognized that the role and structure of the combustion furnace volume of the furnace made high, and the use of furnace arch and secondary air, thereby improving combustion efficiency. 2, coal oil and generator power exceeds 6 MW, the size of these layers grate burner is too large, complex structure, easy arrangement, so 1920s using the burner chamber, the combustion chamber coal and oil burning furnaces . After the coal ground by the mill coal burner combustion injected into the furnace, then the capacity of the generator is no longer limited by the combustion apparatus. Since the beginning of the Second World War, almost all of the power plant boiler using the burner chamber. Pulverized early produced using U-shaped flame. Burner pulverized coal flow jetted to fall in the furnace, and then turns to rise. Later appeared cyclone burner front wall arrangement, L-shaped torch flame in the furnace. As the boiler capacity is increased, the number of cyclone burners also begins to increase, may be arranged on both sides of the wall, the back wall may be disposed on the front. Around 1930 he appeared in the four corners of the furnace and is arranged mostly circle tangential DC combustion burner. 3, after the Second World War, oil, cheap oil, widely used in many countries have begun to oil-fired boiler. Automated oil-fired boilers easily improved. After the 1970s oil price increases, many countries once again turned to the use of coal resources. At this power plant boiler capacity is also growing, combustion apparatus requires not only complete combustion, ignition stable, reliable operation, good low-load performance, must also reduce pollutants in the exhaust.
