What condensing boiler water scale hazardous due to the condensing boiler is located in a different region. There are differences in the water hardness. When high chloride content and sulfate in water, in the condensing boiler as the water will continue to evaporate, so that they go beyond the limits of its saturation concentration is precipitated, and the drum, adhering deposition of water wall, and gradually form hard , insoluble in water scale. Multi scale deposited within the drum and the heating surface of the water wall, causing great harm to the condensing boiler and its operation. The main harm is done to scale: (1) scale is a poor conductor, its thermal conductivity is 1/5 of steel, the scale will affect the heating surface thermal conductivity. The increased thermal resistance due to heat caused by fuel waste, reduce the thermal efficiency. (2) due to the poor thermal conductivity of scale, fuel combustion heat is not well transferred to the water by the metal surface, resulting in the metal heating surface temperature increases overheating, reducing the structural strength of metal, and causing the drum is deformed Wall table, drum kits, tube wall section is reduced, which can result in poor circulation can not even over the water and cause water wall tube burn accidents, severe cases can lead to burst pipes. (3) When people using a chemical or mechanical cleaning descaling, will cause corrosion of the metal of the inner wall injury or reduce the life of condensing boiler.
Steam boiler operation which valves contain? As we all know, such as large-scale boilers special equipment, then we need a lot of instrument valves, especially valves, it requires a lot of species, and the effect is different. Because the steam boiler high efficiency industrial autoclave through the heat exchanger, the heat exchanger feedwater steam, heated water, then heating, heating, bathing, production purposes. Today to introduce you to a steam boiler system runs all soft drinks which valves need help. A valve type boiler comprising: 1, 3 four major categories of safety accessories: safety valve, the drain valve (valve), water level gauge (water column unit). 2, water supply system: gate valves, check valves, safety valves, discharge valve. 3, the steam system: stop valve, a ball valve (plug valve), the drain valve, safety valve, steam trap. Second, the role of the valves: valve - Overpressure discharge valve to prevent the system - or sewage water in the discharge water level indicator system - boiler water level observation shutoff valve - off, the control channel steam trap - keep the discharge pressure utilization system water valve - valve to prevent backflow of water supply - flow control
With the completion of the early stage of our economic construction, our country has increased its investment in people's spiritual and cultural efforts, and with the demands on the environment, coal-fired boilers are the major air pollution households, and they have been strictly put into practice in the country at the beginning. And what's the difference between its replacement fuel-fired boilers and gas-fired boilers?
Around at 10:12 on February 28, 2019, Zhangjiakou City Chabei Management District Kai Austrian Energy Management Services Ltd. Taiwan 15 tons of steam biomass boiler drum due to the control zone tearing a serious accident, killing three people the death of four people were injured.
Currently seven injured in hospital emergency treatment, cause of the accident is still under investigation, rehabilitation disposal is also an orderly manner.

At 15:30 on January 2019 May 2009 55 points, Zhangjiakou City Hall Ltd. Hong Mei generating boiler scalding accident, three people were killed and one injured.
Boiler special equipment is clearly defined our country, whether it is manufacturing, purchase, installation, operation or maintenance, have strict operating guidelines. Now many have adopted new boiler intelligent control, operational safety compared to conventional boilers, more convenient; but that does not mean foolproof, vigilant and master the correct method of application, in order to minimize accidents frequency. After all, the cost of each accident are living lives.
