How much is the cost of the transformation of industrial recovery boiler in paper industrys, industrial boilers transformation costs how much money? With increasingly stringent environmental policy, a lot of coal-fired boilers are in need of rehabilitation. For the cost of the required current business situation will have to see the boiler, if time is too long, then it has no value transformation, and not as a direct boiler for a new one for direct production. With more and more serious air pollution, people's environmental awareness is gradually increased, the country has issued a series of policies to combat air pollutant emissions, on the industrial boiler industry, small coal-fired boiler flue gas emissions contained in the dust, sulfur and nitrogen oxides can cause serious pollution of the atmosphere. Therefore, the coal-fired boiler to gas boiler has become a way now widely used. How much is the cost of the transformation of industrial boilers, to be determined according to need of rehabilitation component, location, and so on. In general, industrial boilers convert almost need to start from the following aspects: 1, removal of former industrial boiler auxiliary equipment; 2. Calculated by the heat transfer in the furnace, the furnace geometry is determined, the center position of the flame furnace, the furnace is re-injected, and after the original arch tube is made on the basis of the original slope. 3, installation of blast doors; 4. industrial boiler equipment 1.5 times the working pressure of the hydraulic tests carried out. Under normal circumstances, the pressure component of the boiler furnace should not be changed as much as possible, and only furnaces and furnace wall arch reform should be carried out locally.

Using an economizer does not just prevent heat loss — it can also extend the life of therecovery boiler in paper industry. Temperature changes caused by using cooler feed-water can create wear and tear on theboiler over time as the fittings heat and cool down cyclically. When the feed-water is heated, the temperature differential is less extreme, putting less strain on theboilerand giving it a longer operating life. Since a largeboilersystem can be expensive to repair or replace, this adds to the overall savings on theheating system.
