fire tube boilers drawings

Steam fire tube boilers drawings at the Sheung Shui should pay attention to things steam boiler before ignition to conduct a comprehensive inspection of steam boilers, steam boilers Sheung Shui things should note the following requirements: 1, the steam boiler water quality requirements, if the point of use water boiler water hardness is too high should be supporting, supporting demineralized water hardness can reduce scaling in the boiler tubes, thereby increasing the life of the boiler to reduce operating costs. 2, Sheung Shui, when should slow to add water inside the steam boiler feed water temperature is not too high. 3, add water, not too much, as the temperature of the water will continue to increase expansion, resulting in waste. Generally, add water to the normal water level of the water line also is the middle line on it, now supporting the steam boiler above all intelligent devices in Sheung Shui, simply open the smart addition of water it can be had. 4, to put inside the boiler economizer and air inside the boiler duct excluded when water was added. 5, after the Sheung Shui to see whether the water level in the water level dropped, there may be drain valve not closed tightly reason, you should check the steam boiler population during the Sheung Shui, welding flanges, pipe is leaking phenomenon exists, if found leaking immediately stop adding water and appropriate treatment.

First, the lack of water causes 1, feed water control device failure, or failure of feedwater automatic control not detect. 2, operator negligence, insufficient water level monitoring, adjustment is not timely or misuse. 3, fire tube boilers drawings sewage, valve leakage, excessive sewage. 4, water level gauge, steam or water flow meter flow meter indicator is incorrect, erroneous determination that the operating personnel and an operation error. 5, water pressure drops. 6, water wall or economizer squib leakage. 7, the boiler load plummeted. Second, the boiler water solutions 1, the wash drum water level control and to check whether it is correct. 2, the water regulating automatic to manual, automatic not administered as electric, electric can be manually changed, and increase the boiler feed water. 3. After the above treatment process, remain within the drum water level decreases, and economizer of the boiler should check whether the door tight drainage, water leakage when large impact damage economizer and circulation water is found, the scheduler should consult stop furnace. 4, such as to take measures to restore the water level, the water level continued to decline and reached a low water level allowed, the control room should be reported, and reduce boiler load. 5, as the water level continues to decline, and disappear when the Water Level Indicator, the boiler unit should immediately stop running, Sheung Shui to prohibit the boiler. These are the causes of water shortage and solutions for several reasons, I believe the above explanation can help us better to solve this problem, but also can effectively avoid the occurrence of this phenomenon.

Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type fire tube boilers drawings paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.

Factors affecting the safe operation of the daily atmospheric fire tube boilers drawings which: (1) When atmospheric pressure using the direct pressure hot water boilers and water heating system or closed loop. That is, on the boiler body with the atmosphere of the exhaust pipe as a return pipe use, the boiler water pressure is always in full state. This closed loop harm in two ways: The first is when the water temperature is too high furnace, steam generated can not be excreted, so the pressure will continue to rise, explosions and spills can happen at any time. Second, even if the boiler water temperature is not high, it does not produce a large amount of steam, but the role of a circulation pump, the boiler body is subjected to high pressure hot water circulation.
