This technique is performed by coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of the suspension increases combustion energy can be obtained a certain rate. As for boiler fuel, gas type, you can replace the old with the new energy-saving burner, behind the burner to be transformed.
Industrial gas steam fired boiler price in antarctica for industrial use industrial gas steam boiler is a low-pressure gas steam boiler, but its high thermal conductivity temperature of the liquid inside, and the liquid explosive is mostly, if working in industrial gas steam boiler thrown thermally conductive fluid leak and cause a fire or even a large possibility of an explosion, which is very dangerous, so run industrial gas steam boiler safety is often worth the length of the face. Because the range of high temperatures (above 320 ℃), low voltage (0.3 to 0.5MPa), the heating temperature can be precisely controlled, it can replace the original steam boiler heating. Industrial gas steam boiler is heated up to a temperature of 350 ℃, molten salt furnace is heated up to a temperature of 530 ℃. Because the ash can not be produced by industrial combustion gas steam boiler fuel gas, if the gas and air mixture into the furnace is injected within a certain range may explode. Gas steam boiler operating temperatures above 400 ℃ oil and molten salt heat transfer medium, having a molten salt heat steam than the gas lifetime advantages, but otherwise are at a significant disadvantage, in particular the complexity of running the system.
You must know the fired boiler price in antarctica energy problems (induced draft fan power consumption rate, steam consumption) draft fan causes problems 1.1 boiler flue dust and fouling, in particular air preheater fouling, resulting in increased resistance to smoke duct . 1.2 boiler flue, tail heating surface and dust leakage. 1.3 Leakage Rate large air preheater. 1.4 furnace excess air coefficient is too large. 1.5 unit load changes, run the adjustment is not timely, resulting in furnace pressure is too large. 1.6 unit load or low frequent starts and stops. 1.7 coal into the furnace worse, from the design value. 1.8 low efficiency filter. 1.9 draft fan blade badly worn, low operating efficiency. 1.10 fan outlet flue gas desulfurization big resistance. 1.11 soda boiler pipes for leaks. 2, 2.1 to 2.1.1 operational measures to solve the problem of the strict implementation of soot blowing system to prevent the heated area ash, blocking ash, flue gas system to reduce resistance. 2.1.2 holding the induced draft fan, the flue gas separator baffles and dampers in the fully open position. 2.1.3 The experiment showed combustion boiler, proper control of excess air in the furnace. 2.1.4 adjustment chamber negative pressure, air leakage reduction furnace and the flue. 2.2 routine maintenance and testing 2.2.1 induced draft fan performance test to determine the optimum operating point and efficient workspace. 2.2.2 boiler, air preheater, a flue, ESP and other system leakage inspection, process. 2.2.3 timely check processing chassis, shaft seal leakage. 2.3C / D repair, eliminating defects 2.3.1 down strict accordance with movement clearance adjusting fan. 2.3.2 induced draft fan blade defect action elimination hand vane opening adjustment. 2.3.3 Importers and induced draft fan baffle opening check. 2.3.4 duct tightness check process. 2.3.5 wave plate replacement air preheater, rinsed sector plate gap adjustment. 2.3.6 eliminate dust defects and improve collection efficiency. 2.3.7 clean flue gas desulfurization system, flue resistance is reduced. 2.3.8 eliminate soda boiler pipe leakage defects. 2.4A / B repair and transformation 2.4.1 Check and repair the fan blades, replace seriously damaged blades if necessary. 2.4.2 for energy saving fan efficiency below 75%. 2.4.3 The fan motor frequency transformation. 2.4.4 of the precipitator, if necessary, transform and improve collection efficiency.
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.Free Chat
