Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Refers to the operation of the steam boiler is refluxed pressure activated device circulating pump, the circulating pump outlet, inlet, outlet, and the system, it is in the normal range. Circulation pump run for 30 minutes. After the stability of the system, the next step. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition.

Increase productivity how to choose boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.

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.
