moving horizontal steam generator

The steam generated by the boiler is generally measured in tonnage, but the steam turbine power generation is calculated by heat, and the two can be converted: generator electric power MW = boiler tonnage × steam per ton × steam turbine efficiency × generator efficiency. The steam enthalpy depends on the parameters of the steam. The pressure and temperature of the steam are different, and the enthalpy value is also different. It is generally considered to be 0.7. The coefficient of steam turbine efficiency and generator efficiency depends on the power station unit system.

Description electric heating boiler 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.

Gas-fired steam boiler meets the requirements of environmental protection biomass fuel is a highly polluting fuel yet? Gas-fired steam boilers can use in the city do? According to environmental requirements and implementation of standards, Chinese Ministry of Environmental Protection has responded, reads as follows: 1. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees gas boiler the ignition system functions to ignite the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Hot water boiler boiler assembly PC-style controller, all functions are stored on a smart chip, intelligent boiler, digitization, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stop; large screen fonts display temperature, boiler water temperature at a glance. Agriculture and forestry wastes (straw, rice husk, sawdust, branches, etc.) are used as raw materials. Under certain conditions, the use of special equipment for processing rod-shaped, bulk or particulate biomass briquette, can effectively improve the combustion performance of the agricultural and forestry residues, and the sulfur, nitrogen, low ash content, can be used for supporting special combustion equipment, and clean and efficient combustion. It produces sulfur dioxide, nitrogen oxides and soot less, not polluting fuels. Second, the city promote the use of biomass briquettes should take full account of local ambient air quality control requirements and the actual situation of fuel supply. In the case of city gas supply can not meet demand, biomass briquettes as an alternative fuel, fuel-emission standards should be required, and promote the use of scientific evidence in large urban centers, the more stringent requirements on atmospheric emissions of pollutants. 3. In terms of promotion and application of biomass briquette, briquette raw material to strengthen the supervision and management of the production and use of right. Developing local standards and technical specifications and biomass briquette combustion supporting special equipment, which regulate the production and use; in the application process, focusing on the production of dioxins monitoring; production and sales of biomass briquette combustion equipment and dedicated support unit shall have appropriate qualifications. Products should be certified by the quality, safety, environmental protection, energy conservation and other relevant authorities and comply with the relevant technical regulations and standards. Environmental protection is a basic national policy of China. Take the road of sustainable development has become a basic strategy of economic and social development of our country. To further implement the "People's Republic of China Air Pollution Prevention Law," "People's Republic of China Energy Conservation Law" and the "Provisional Regulations on Boiler and Pressure Vessel Safety Supervision." Comprehensive Plan and in accordance with the requirements of the country atmosphere. Natural gas boiler manufacturers strengthened pollution control and energy conservation boiler safety. Gas-fired steam boiler to achieve a low-carbon environmental requirements. Replace coal-fired boilers with gas-fired boilers help save energy and improve the environment, and has been included in the Ministry of Environmental Protection and China Environmental Protection Industry Association, the state's key environmental protection practical technology projects. Boiler is an energy conversion device. The boiler is a chemical energy input fuel and electrical energy, thermal energy output at a certain boiler steam, hot water or organic heat carrier. Pan intended to refer to heating of the water container on the fire, the chamber means where combustion of the fuel, a boiler comprising a furnace and two pot portions. Hot water or steam produced by the boiler can provide the required heat energy directly to industrial production and people's lives can be transformed into mechanical energy through a steam power plant, or by a generator converts mechanical energy to electrical energy. Provide hot water boiler known as hot water boilers, mainly for life, seldom used in industrial production. Boiler steam is known as steam boilers, typically referred to as boiler, it is mainly used for thermal power plants, ships, locomotives, and industrial and mining enterprises.
