The heat recovery electric steam generator is important to the national economy electricity energy supply equipment, machinery, metallurgy, chemicals, textiles, paper, food and other industries, as well as industrial and civil heating boiler needs to supply large amounts of heat. Boilers using fuel combustion energy released or other energy to the working fluid (heat carrier intermediate) is heated to a certain device parameters. For heating the water to make it into the boiler steam is known as steam boilers, also known as a steam generator for heating water to make them more water into the boiler temperature, known as the hot water boiler for heating of Heat Transfer Fluid It called boiler organic heat carrier boiler. From the energy point of view, the energy conversion device is a boiler. In a boiler, a chemical energy (fuel) storage by the combustion process into the combustion products (flue gases and ash) contained some heat, then the heat transfer process by transferring heat to the intermediate heat medium (e.g. water, and steam), it relies on the heat transport device to heat. This intermediate heating medium to transfer heat energy belonging to the second, because its purpose is to provide a device capable Into energy. When the intermediate heating medium for heat conversion in a thermal power machine, the work called quality. If only the intermediate transmission to the heating medium heating device to provide heat for heat utilization, is usually referred to as heating medium. It can be divided into four categories according to their use boiler power plant boilers, industrial boilers, marine boilers and locomotive boilers. The first two categories, also known as fixed boiler, because it is mounted on a fixed basis and immovable. The latter two are called mobile boiler. This book presents a stationary industrial boilers. The boiler in three main processes: (1) the fuel combustion in the furnace, which can be released in a chemical storage form of energy, the flame and products of combustion (flue gases and ash) having a high temperature. (2) high-temperature flame and smoke for heating the working fluid (heat medium) by heat transfer. (3) working fluid (heat medium) is heated to raise its temperature of vaporization or saturated steam, or further heated to become superheated steam. The above three processes are interrelated and simultaneously, to achieve the conversion and transfer energy. Along with the energy conversion and transfer of flow and also the changes of: (1) working fluid, for example water supply (or return> into the boiler, and finally reveal the form of steam (or hot water) (2) fuel, for example. combustion of coal into the furnace, which together with the combustion of the combustible portion of the original moisture content of the flue gas into which the original residual ash is ash-containing. (3) air into the furnace, wherein the combustion of oxygen to participate in the reaction, the reaction and the excess air the remaining inert gas is mixed in the flue gas is discharged. FAW water system, a coal ash smoking system is a system of wind two three main boiler system, the work of these three systems are performed simultaneously. this typically fuel and flue gas side process (involving the combustion, heat, slag, gas flow, etc.) collectively referred to as a furnace process; the process performed by water, steam which side -1 (steam and water flow, heat, vaporization, water separation, thermo-chemical processes, etc.) collectively referred to as the pot process. the main parameters of the boiler, the boiler comprising a heat generation quantity and quality indicators of both. as the main parameters of the number of steam boilers and steam production of the steam pressure, temperature, water the main parameters of the boiler Hot water flow rate and pressure of hot water temperature.

Description electric heating heat recovery 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.
