Second Session of the CPPCC National Committee Session of March 5 press conference held in the afternoon, the CPPCC National Committee of Population, Resources and Environment Committee, Democratic National Construction Association Central Committee, Environmental Management Division of the Ministry of Ecology Environment Atmospheric Liu Bingjiang said: Last year, resolve more than 30 million tons of steel production capacity, 810 million kilowatts of coal-fired units basically reached the national emission levels of natural gas, built the world's largest clean coal power base, out of 1.3 million units in industrial furnaces, coal accounts for the country's primary energy consumption the proportion of first time below the 60% to 59%, and turned off the small coal-fired boilers 23000 units.
At present the country has completed a preliminary air pollution control goals, the future will continue to promote coal-fired boilers governance, and the introduction of more stringent emission performance standards of air pollution.
Small boiler water volume, faster heat transfer, either warming or boost quickly. After 5 minutes the ignition to start the output of hot water and steam required, and water separator with a high performance, to ensure the quality of steam and hot water.
Using Method 2 tons of gas steam boiler 1, to check before the start of attachment deaerator water level control valve, water level alarm, steam pressure control valve, seal means (previously filled with water) and a variety of instrumentation has been in the supervision normal state, does not meet the operational requirements should be adjusted. 2, slowly start the pump inlet, inlet temperature and pressure recording. 3, the water level regulating valve before the valve is opened, the bypass valve is closed. 4, the exhaust valve slightly open top. 5, opening the upper valve tube steam heating tank, the heating temperature in the tank. 6, the valve is opened the steam pressure regulating valve for steam heating, inlet pressure and temperature recording 7, when the water level has reached the level indicated in Table normal level (1/2 water gauge), a thermometer indicator tank is about 104 deg.] C, starting feed pump, open the water supply valve, from start to normal supply about half an hour. 8, deaerator during normal operation, the upper portion of the exhaust valve opening degree of about 1/4 turn around. 9, the steam supply valve is closed upper deaerator steam heating tubes. 10, at regular intervals laboratory water, water's oxygen content, record the value of various supervision instruments.
What rely on hot water boiler in abu dhabi circulating hot water boiler and sewage notes, this is a particular kind of boiler, but also the product website, it is necessary to be familiar with and understand, to find out what it is and how to correct and reasonable use, this ensures that products are a good use of effects and to achieve full utilization, but also to avoid misuse and other issues, they would benefit from. 1. The hot water boiler depends on what forced circulation and natural circulation? Hot water boiler, which is a thermal energy conversion device capable of providing hot water, when it is the transfer of heat to the fuel combustion in the boiler water, boiler water temperature rises to a certain user for heating or life water. In general, the boiler inlet and outlet flow is water, which is carried out by forced circulation pump pressure. If it is natural circulation, the difference is the weight of the body against the boiler water temperature to achieve a different result. 2. Whether the new hot water boiler cook stove before you start using? What are the requirements for water quality that is running? Until a new hot water boiler started, is to be boiling out of work, so on a question, the answer is yes, the aim is to remove the protective film in the boiler rust, oil and metal surface, thus, make it hot water boiler and smooth running. When the boiler is running, is required to control the quality and the use of demineralized water, the PH value in boiler water, to be maintained within the range of 10-12. 3.1.5 tons of hot water boiler, which is what the cycle of water and other notes? 1.5 tons of hot water boiler, which heat supply to the boiler in accordance with the calculation, it should be 1.05MW hot water boilers, hot water boilers are small tonnage, which generally is not the high pressure high temperature water, particularly in the standard parameter, is 1.6 / 150 / 90,1.6 / 130 / 70,1.25 / 130/70 and 1.0 / 115/70, the first digit for the boiler pressure, the middle number is water temperature, return water temperature is the last digit . And this kind of situation replenishment boiler, have a great relationship with the boiler system, it should be considered comprehensive, and this point can not be ignored. 4. The hot water boiler blowdown, whether there are considerations? Hot water boiler blowdown, which is there are some considerations that are specific to: the sewage before work is performed, the water level in the boiler should be adjusted slightly above the normal water line state, there should be no flow of sound in the outfall. Sewage pipes outside the touch blowdown valve, the temperature should be within the normal range, if an exception should be resolved in time, by hand without delay.
