Recently, we learned that the city of Zhangjiakou Yuxian environment departments to carry out a special investigation of coal-fired disadvantage of water tube boilers, coal-fired boilers have complete control of the number of the county, painstaking, and practical coal-fired boiler renovation work to ensure safe and stable environment of the area.
The action focuses on the central heating pipe network has access to the dismantling of coal-fired boiler units, still use coal-fired boiler heating key units of 18 coal quality, coal to electricity station uniform implementation of the 1001 residents of coal-fired heating boilers civilian electric boiler furnace demolition and safe usage, the main city of 39 sets of bath boiler operation of treatment facilities, boiler demolished nine agriculture-related enterprises from coal to gas and gas safety carried out a detailed examination. Unit 4 of the use of substandard coal, the filing be investigated according to law, for gas safety problems 9 agribusiness, notify the county Emergency Management Agency and the territorial towns to regulate the management of its duties, to further prevent security incidents from the source .
Gas hot water boiler and heating water for people living essential energy equipment, because of its specificity performance of the need to comply with strict safety operation of the Code. Then, gas hot water boiler needs to run how to protect their safety performance?
1, after carefully checking gas hot water boiler water supply, drainage, gas pipe fittings, safety valve, pressure gauge, water level gauge is sensitive Haoshi before work, make sure it is safe to operate.
2, with both hands to manipulate when Sheung hand to open the door of water, whereupon the other hand the water injector and valve open, water flows naturally into the furnace. When stopped, the steam valve should be closed first, then turn off the water door, switch and valve, the front face must escape in order to avoid accidents caused by soft drinks out.
3, gas hot water boiler in operation, to pay attention to all parts of the check, and observe whether the water pressure in the normal range. Fireman can not leave their posts without permission, when night work, avoid dozing off, but not allowed to sleep, to avoid accidents. Boiler blowdown, a class must be properly adjusted before the sewage water level, slightly higher than the normal water level of 2/3 of the standard, then the sewage.
4, the water level table class must be flushed once. Flushing, according to a predetermined program, the first closing valve and open the drain valve, flushing steam valve, when attention is blocked steam origin; steam valve is then closed, when attention is blocked antecedents water. Flushing valve, until the water becomes steam, some a little longer, in order to guarantee no false water level. Hot water boiler fuel gas safety checks must be carried out to prevent the presence of explosive materials in the fuel to prevent the risk of explosion.

Greenhouses have very strict requirements of humidity and temperature control, which directly affect the the plants growth and earnings. Zhengzhou Boiler Co., Ltd has a long history of providing high efficient and reliabledisadvantage of water tube boilers for thegreenhouseowners that demand uninterrupted service when it comes to their domestic water and hydronic heating needs.
The disadvantage of a water tube boiler is that the capital cost is normally higher than the equivalent fire tube boiler and, depending on the size, it often has to be constructed on site, which can add to the costs and timescale.

The advantages of water tube boilers are. Consider a fire tube or smoke tube boiler and a water tube boiler with similar evaporative rates the water tube boiler would be compact and relatively light by comparison and its water content would be about 7 tonnes or less compared with the smoke tube or fire tube boilers 30 tonnes. With double casing radiation loss can be cut to 1 % or less.

Apr 20, 2012 · Disadvantages. Major disadvantages associated with fire tube boilers are mentioned below: As a general rule, the maximum output generated out of fire tube boiler is around 27 000 kg / h. In case of high steam requirements, one needs to combine multiple boilers together. Besides, the fire tube boiler systems are not capable of working with applications which involve high operating pressures i.e. beyond 250 psig.

Apr 23, 2018 · Water Tube Damage: Boiler Tube can be damaged if there is any dust in the feed water. Because it blocks the water circulation. The deposition of salt and sediments in the inner surface of the Water Tube is a common problem for this type of boiler. Water Level: Water Tube Boiler uses less water and for this reason, the water level needs to check randomly. A makeup water pump is used for supplying the necessary water.
