Oil-fired and gas-fired boilers can use both gas fuel and oil fuel. The fuel adaptability is very wide and can be normally used in the whole country. And the boiler operation efficiency is very high, a year down, at least can save tens of thousands to hundreds of thousands of fuel input costs, thus favored by users.
For boiler users, the service life of oil-fired and gas-fired boilers is very important, which is a very important data to measure the cost performance of boilers. But in fact, want to prolong the service life of oil and gas boiler also has certain methods, let zheng Zhou Fang Fast boiler factory boiler technical engineer Song Gong to give you the answer.
First of all, we must control the water quality in the oil-fired and gas-fired boiler to prevent the boiler from heating unevenly caused by scaling. The harm of boiler water quality is mainly scale, corrosion, steam quality deterioration, especially to the existence of hardness substances in the water, in the boiler and water contact heating surface will generate some poor thermal conductivity and hard solid attachment, this phenomenon is called scale. Because scale thermal conductivity is hundreds of times worse than that of metal, it is easy to cause local overheating deformation of metal, bulging, tube explosion and other accidents, affecting the safe and economic operation of boiler; Clog pipes, destroy water circulation, affect heat transfer, reduce evaporation capacity, waste fuel, produce corrosion under scale, shorten boiler service life.
The second point is to control the heating rate of the boiler to avoid excessive thermal stress and metal fatigue.
Third, to the boiler feed water oxygen removal, prevent oxygen corrosion, such as the water quality of the furnace becomes poor, you can drain part of the furnace water. You also have to control the iron ions. The most important point, to control the boiler temperature, boost speed.
