A precio calentador o boiler de gran potencia industrial operation must be controlled and stable operation of secondary causes of boiler steam temperature control stability of a secondary steam temperature has important implications for safe and economic operation of the unit. When the steam temperature is too high, it can cause overheating, a portion of the metal to reduce the strength of the reheater, and the steam turbine pipe cylinder and a rotor, resulting in shortened life of the equipment. Severe over-temperature, it will also enable the heating surface blasting. When the steam temperature is too low, the effect thermodynamic cycle efficiency, and a steam turbine final stage blades at excessive humidity, severe water hammer may occur, resulting in damage to the blade fracture accidents. When the steam temperature substantially sudden rise dump, large thermal stress is generated in addition to the heating surface of each weld and the outer part of the boiler is connected, will cause the relative displacement between the cylinder and the rotor of the turbine increases, i.e., the expansion difference increases, severe or even static friction wheel and the separator, causing severe vibration. In addition both sides of the turbine steam temperature deviation is too large, both sides will uneven heating turbine, uneven thermal expansion. Therefore, the operation of the boiler steam temperature to closely monitor, analyze, adjust, control steam temperature stability with the most reasonable method.
Autumn occasion fruits. September 2 this year, China-Africa Cooperation Forum Beijing Summit smooth opening of the meeting, determine Dongfang Electric Power signed with Egypt Egypt Hanna Wei six 1100MW of clean coal combustion and coal pier supporting the EPC project general contract. The project is currently the world's largest clean coal projects, but also Chinese enterprises for the first time will have ultra-supercritical clean coal technologies with independent intellectual property rights to the world.
1100MW, is the world's largest single coal units capacity. Egypt Hanna Wei 6 × 1100MW coal-fired power plant will clean 6 stand-alone capacity of 1100MW coal machine components, which will become the world's largest clean coal power plant. The total size of the project is about $ 4.4 billion. Joint venture will work final contract negotiations and other business and financing as soon as possible with the Egyptian company.
The project won the bid total amount (by share of joint venture company 50% equity share calculation) accounted for about 18% of the company's 2017 annual revenue, the company will confirm the actual sales income in accordance with the implementation of the project.
The project will be built in the Red Sea tourist area, demanding for clean and green. The power plant project hosts supplier Dongfang Electric and Shanghai Electric said its independent research and hosts will use the world's most advanced high-performance ultra-supercritical power generation technology and near-zero emissions of environmental technology. Advanced technology is mainly reflected in the high-efficiency coal-fired power generation. From the current standards, the national coal requirements will kilowatt needed to control the 300 g or less, and this project per kilowatt coal consumption less than 280 grams, the thermoelectric efficiency of up to 45%.
Egypt was among the first to support one of the countries "along the way" initiative in China. The project will also "along the way" along the clean coal-fired power station construction played a good role model, and further promote the high-end manufacturing to promote the development of China's power sector outwards.
Whether the precio calentador o boiler de gran potencia industrial emissions to be calculated into the boiler efficiency? Thermal efficiency of the boiler is the effective use of heat fed to the boiler and the boiler heat ratio. It refers to the effective use of the heat absorbing heat boiler water and steam flowing through the respective heating surface. Boiler blowdown water has absorbed heat into the boiler, it should be included in boiler efficiency.
Condensing gas precio calentador o boiler de gran potencia industrial was good than conventional gas boiler it? Ordinary gas boiler thermal efficiency of around 90%, then 10% of these heat losses are going up, along with the exhaust waste, ordinary gas boiler flue gas temperature at 100 ℃ above, and condensing gas boiler exhaust gas temperature may be 40 ℃, it may be sensible heat in the flue gas to absorb. Since the gas-fired boiler using natural gas, when burned will produce a lot of water vapor, which can liquefy if part, will release a lot of heat, condensing gas boiler did, which absorbed the latent heat in the flue gas, so that together, LHV is calculated in the thermal efficiency of 108.9%, higher than ordinary condensing gas boiler gas boiler thermal efficiency of 20%.
