Gas leading boiler manufacturers full of water occurs, the occurrence of how to deal with gas boiler filled water, a high level alarm will sound an alarm level signal, beginning with the water vapor, decreased steam quality, increased salinity, superheated steam temperature drops. Severe full of water, or even furnace water into the steam line, steam line caused water hammer occurs, resulting in a serious impact to the boiler. When full of water for the boiler this situation occurs, fast Boiler summarize the following knowledge points, for your reference. First, the phenomenon when the boiler is full of water 1, the water level is not visible or not, a high level alarm; 2, steam temperature decreases, main steam isolation valves and the turbine inlet valves visible white steam; 3, turbine or steam pipes water hammer; 4, the normal water flow is not greater than the steam flow. Second, a full water Boiler feed water is automatically jump manually, resulting in abnormal increase of water supply; 2, or drum set on the safety valve steam header, resulting in up water or with water; 3, ultra-evaporation boiler load more, happens priming. Third, the full boiler water treatment 1, boiler steam pressure and water pressure to normal, while the drum water level rises, exceeds + 50mm, should take the following measures: wash drum were compared with the two water gauge to check their instructions are correct. Water supply from the automatic to manual adjustment, and shut off the manual door small total feedwater adjusted to reduce the amount of water to the door. 2, if After the treatment, the inner drum water level is still rising, exceeds + 75mm, the following measures should be: open the door for emergency drain drum should be put to the normal water level water level shut down immediately. The steam temperature condition, turn down or turn off desuperheating water door, door open and main steam superheater tubes hydrophobic hydrophobic gate. 3, when the boiler full of treated water drum water level continues to rise, and exceeded the upper drum level table when the water level is visible, the need for emergency shutdown, as soon as possible with the main pipe splitting, immediately stop the water, recycled to open doors, to strengthen boiler drain, and note the emergence of drum water level gauge upper water level, the water level to be put to the normal level after closing. After the normal Standby furnace, obtain professional fireman who consent, it may furnace stoked operation. 4, such as the water level in the steam drum water level tables invisible, not in time, should take the following measures: wash drum were compared with the two water gauge, check if the indication is correct. Full drum water level tables turn on the water door, turn on the water and then slowly close its doors, as there is water in the water table appears, and water levels continue to rise full of tables full of water and has not been proven boiler water level gauge steam over the side of the tube, press the emergency shutdown process. Open the door turn on the water table level, and slow to close its doors after the turn on the water, the water level in the water table invisible. To prove a serious full of water, soda and then close the door, turn on the water to open the door, the water level of the water table memory after the release to do, turn on the water shut the door immediately. Ajar quickly and valve inner water table level occurs, and filled with water, before this time has exceeded the determination level of the steam drum level side through the tube sheet, emergency shutdown should be treated as soon as possible and the manifold splitting. When the water level in the boiler accident occurs, it is difficult to judge if the water level should be shutdown immediately. After a boiler shutdown called water method called water, check the water level in the drum.
Xuchang City in the recently released "2018 campaign of air pollution control plan", especially for the governance of the city's leading boiler manufacturers was planned.
Xuchang coal-fired boiler governance objectives:
In Xuchang complete basic steam 10 t / h coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, out of a planned urban area 35 steam tons / hour and coal-fired boiler.
Coal-fired boiler subsidy:
(1) the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;

What to do before checking gas leading boiler manufacturers start? Since the gas boiler is a steam and pressure apparatus having a container, so if if not in accordance with the safety rules will easily lead to an accident during the operation, so that workers in the operation of gas boiler according to a certain regulation program and to execute the relevant ready to run and shift recording. Following on from the gas boiler manufacturers to introduce high stability oven before start check what to do. 1. Check the appearance of the boiler and gas pressure at the time ready to start gas boiler fireman on duty should first do a comprehensive inspection, including the appearance of the boiler, valves and various joints, and also check the gas pressure, ensure that the pressure value is not within the normal range is too high or too low, after checking the normality of the gas supply valve to open. 2, check the water supply system in the gas boiler when burning is to have water inside, otherwise the danger occurs. So, before you start the furnace fireman who should check the water supply system, the pump can see Sheung Shui, Sheung Shui, if you can not normally necessary to play an open air release valve, pump can know until the start Sheung Shui, and then open the water supply system each valve. 3, check the water level inside the boiler if the gas too much water or too little will affect the safe operation of the boiler, do check the water level before the start of the furnace is very important, because the water level of the role is to be able to let the fireman keep abreast currently there is also much water boiler. So, before the gas boiler water level started to look at the position is normal, but also depends on the water level and the water level meter-bit color plug is in the open position, to avoid the phenomenon of false water level, and then observe whether the water shortage, if the lack of water can manually Sheung Shui. Able to meet the customer's gas boiler manufacturers tell you, that's the matter before the start gas-fired boiler furnace fireman who needs to be checked, in addition to these, the fireman who also check the windshield on the flue and to ensure that all in the open state. Only when all aspects are carefully check the boiler officially started well before gas-fired boiler.
