comparison of fire tube and water tube boiler

Winter is the peak heating heating, but also prone to accidents of special equipment such as comparison of fire tube and water tube boilers. To effectively prevent and curb the occurrence of accidents, equipment thorough investigation to eliminate safety hazards, Hunan Province to carry out safety hazards investigation work in the province within the boiler, boiler equipment and punishes the security measures are not in place.

Yueyang City bearing the brunt of the provincial government in response to the call for in food, pharmaceutical processing industry, boiler equipment, pressure vessels, pipelines, etc. investigation and remediation, further investigation and security risks, strengthen supervision, which ensures safe operation of special equipment.

Zhuzhou City, the relevant departments to implement the special equipment safety responsibility, collective interviews conducted meetings, some special equipment overdue inspection or rectification in place of business risks not to be interviewed. In order to urge them to get inspection reports in order to restore operation, to ensure the safe use of special equipment. But also warned of these enterprises, if not through legal regular inspections, not only safety and production are not effectively protected, will be severely punished.


For improper situation to improve boiler blowdown Boiler Blowdown policy. While having a bottom surface and a continuous periodic blowdown boiler blowdown both devices require at least once per shift sewage, but also for testing of the boiler water every one hour to two hours, analysis of the index meets the relevant standards, if an found in the detection of excessive should immediately adjust the valve until the index reaches the standard.

Gas comparison of fire tube and water tube boiler leaking how do

For leaking gas boiler, to adopt a different approach according to the actual situation. Generally gas boiler leaking into several areas:

Phenomenon comparison of fire tube and water tube boiler full of water, causes and how to deal with? Phenomenon boiler full of water, causes and how to deal with? Boiler filled with water phenomena: (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 occur water hammer; (4) water flow is not larger than the normal steam flow. Boiler full of water: (1) water supply is automatically jump manually, resulting in abnormal increase of water supply; (2) or the drum set safety valve on the steam header, or causing the water level to rise with water; (3) boiler evaporation overloading or more, it occurred priming. Boiler full of water: When the steam pressure in the boiler and pressure to normal, while the drum water level rises, exceeds + 50mm, should take the following measures: (1) were compared with two wash drum water level gauge to check its instructions is it right or not. (2) from the automatic to manual adjustment of water supply, water supply and close the door manually turned down and to reduce the total water supply amount adjusting gate. After treatment as above, within the drum water level is still rising, exceeds + 75mm, should be carried out the following measures: (1) to open the door for emergency drain drum should be put to the normal water level water level shut down immediately. (2) The steam temperature, the heated reducing or closing off the small door, door open and main steam superheater tubes hydrophobic hydrophobic gate. When the treated drum water level continues to rise, and exceeded the upper drum water level meter water level visible, on emergency shutdown, as soon as possible with the main pipe splitting, immediately stop the water, recycled to open doors, turn on the water to strengthen the boiler and steam drum note an upper level of the water table appears to be put to the normal water level off. Standby normal furnace, to obtain the consent of value, according to Stoke furnace operation. As the water level in the steam drum water level tables invisible, not in time, should take the following measures: (1) were compared with two wash drum water level table, check the instructions are 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. (2) 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. (3) When the water level in the boiler accident occurs, it is difficult to judge if the water level should be shutdown immediately. After the shutdown called by the water method called water, check the water level in the drum.
