With the completion of the early stage of our economic construction, our country has increased its investment in people's spiritual and cultural efforts, and with the demands on the environment, coal-fired boilers are the major air pollution households, and they have been strictly put into practice in the country at the beginning. And what's the difference between its replacement fuel-fired boilers and gas-fired boilers?
How to design a specification of boiler feed water bag filter dust removal device manufacturers to deploy: boiler bag filter is a dedicated industrial boiler precipitator, because of its high temperature, sulfur content, a major problem difficult to maintain the operation has been troubled by the environmental protection industry, in Ding boiler designed boiler bag filter has a unique advantage, it can deal directly with the dusty gas dust concentration of up to 1000g / Nm3 of gas emission concentrations after treatment is less than 50mg / Nm3, so the company focuses dust bag with the industry is R & D, according to the specific requirements of users can meet more stringent emission standards; but also different types of smoke, dust removal using a different filter, to meet the requirements of emissions, it also can be applied to dust one of the conditions in various fields; dust containing pulse valve, is the use of advanced technology, the service life of up to 100 million times; also fully automated type of controller, small air consumption, a thorough cleaning and stable performance. Then the boiler precipitator dust removal system is so efficient performance designers how to design the deployment of it?
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.
To specifically address some of the difficult problems in steam specification of boiler feed water: a basic aspect for the type of boiler, which is why we must all understand, therefore, is not missing any one of them. So, then, in response to this request, it may wish to continue to understand the steam boilers in order to increase the number of professional knowledge, and so they have a new harvest and inspiration. 1. water boilers, steam boilers that can be transformed into it? Water boiler, which is able to transform into a steam boiler, but it should be noted that, after the transformation of matter or the transformation of the former, should be no pressure boiler. Its specific operation, the drum is mounted at the top of the boiler with a pressure gauge, and then install the steam drum at the top of the safety valve, as the steam outlet. Thereafter, the water outlet of the boiler is connected on the drum, so that, the steam boiler can be obtained.[email protected]
