Today’s gas-fired hot water boilers can be said to be an effective alternative to coal-fired water boilers. Fuel-fired gas hot water boilers can burn fuel more fully, have higher combustion efficiency, and the fuel is cleaner after burning. However, when using hot water boilers, we often see boilers with a long age, and there will be very thick scale on the pipes, which are all caused by poor water quality. In fact, water quality is still very important for the use of boilers. Nowadays, more and more fuel oil gas hot water boilers are put into use. With less automation and labor costs, the actual situation of boiler operation may not be very concerned. The harm caused by scale still needs to be understood.
The presence of scale in the gas hot water boiler or the pipeline will affect the efficiency of heat transfer. If you want to achieve the same heat, you need to consume more fuel. At the same time, the heat of the boiler cannot be conducted, which will cause heat to accumulate inside the gas hot water boiler and the pipeline , Or even corrosion and damage to the equipment. If the gas hot water boiler has no scale of 1MM thickness, the heat transfer efficiency of the boiler will be about 5 ‰ less. At the same time, fouling will also greatly increase the concentration of compounds inside the boiler, which is also the corrosion of the raw materials inside the gas hot water boiler. It will also cause blockage at the turning of the sheet metal of the pipeline. Large and medium-sized boilers with a general working pressure of about 17MPA will be cleaned of scale in about 2-3 years.
