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 10t manufacturers condensing boiler estonias 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.
In hospitals steam has many uses ranging from heating water, central heating, laundry, hospital kitchen and sterilization. On average, less than 10% of hospital steam is used for sterilization. Steam is generated by a large central 10t manufacturers condensing boiler estonia and then transferred to distribution points via a piping system.
"Water hammer" is a major factor in the operational life of the boiler affect mainly causes boiler pressure line due to the influence of some external factors (e.g., the valve suddenly closed, the pump unit suddenly stop, etc.) a sudden and distinct change in water flow rate, so there is the risk of water hammer phenomenon.
Use steam 10t manufacturers condensing boiler estonia pressure gauge should pay attention to the following items: 1, rated steam pressure is less than 2.45MPa steam boiler, pressure gauge accuracy must not be both 2. 5; Rated steam pressure large or equal to 2.45MPa boiler, pressure must not be less than 1. 5 class. The dial diameter of the pressure gauge shall not be less than 100 mm to ensure that the operator can see the surface pressure indication clearly. 2. A red line should be drawn on the pressure dial of the steam boiler pressure gauge, indicating the maximum allowable working pressure. 3. Steam boiler pressure gauges should be installed in places that are easy to observe and rinse, and should be protected from the shadows of high temperatures, freezes and vibrations Ring. 4, steam boiler pressure gauge should be checked at least once every six months, after calibration should be sealed. 5, steam boiler pressure gauge connection pipe should not leak, steam leakage phenomenon, otherwise will reduce the pressure indicator value. 6. The range of the steam boiler pressure gauge shall be adapted to the working pressure of the measured components, usually 1.5 times of the working pressure, preferably 2 times of the working pressure. Steam boiler does not have a pressure gauge, the pressure gauge is damaged or the installation of the pressure gauge does not meet the requirements, steam boiler pressure gauge should be stopped when one of the following: 1, broken surface glass or dial calibration unclear; 2, no lead seal, lead seal damage or Beyond the calibration period; 3, when there is no pressure, the pressure gauge pointer of the finite pin cannot be restored to the limit pin, and the data of the infinite position gauge pointer deviating from the zero position exceeds the pressure coat allowed? Poor; 4, gas leak or pointer jump in the meter; 5, other defects that affect the accuracy of the gauge.
