Basic knowledge of boiler water
Doing a good job of water quality is one of the important links to ensure the safe and economic operation of boilers. Because the combustion temperature of oil and gas is high. Most of the fuel and gas boilers (especially imported fuel gas boilers) are small in size and compact in structure, and have high requirements on water quality. If the water treatment is not well done, boiler scaling and corrosion will be formed, not only the fuel but also the fuel. Causes blockages, squibs, etc., and in severe cases, will also form the largest economic loss of boiler scrap. Therefore, boilers for fuel and natural gas need to carefully handle boiler water treatment.
In some other areas, the alkalinity of the water source is relatively high. After the fuel gas-fired boiler is incinerated and heated, the alkalinity of the pot water will become higher and higher. After reaching a certain concentration, it will foam on the transpiration surface, affecting the steam quality; Under certain conditions, if the alkalinity is too high, alkaline corrosion such as caustic embrittlement at the stress collecting portion may occur. Therefore, the alkalinity of the water quality needs to be reduced. In addition, the dissolved solid content is too high, it will also affect the quality of steam, and even cause steam and water to rise. It should be handled by reasonable drainage.
The intention of the boiler water treatment is to remove harmful impurities, avoid boiler scaling and corrosion, ensure steam quality and ensure safe and economic operation of the boiler.
