Coal fired boiler energy conservationWith the increasing costs of resource and awareness of environmental protection,reducing the energy consumption and the heat loss become an imperative matter of the coal boilers and coal stoker boiler. the experts from China-boiler-manufacturer ZOZEN INDUSTRIAL LIMITED give us the following suggestions to achieve that.optimizing the heating way of coal boilersCombustion modes of coal boilers are layer combustion,chamber combustion and boiling combustion,because the space design of coal boilers is not perfect,in most conditions,the fuel can not be burned sufficiently,so,changing the type of coal stoker boiler and improving the combustion condition are the basis of the normal operation of coal boilers.Increasing the combustion efficiencyFor the layer combustion of large coal boilers, according to the characters of staged combustion and different consumption of coal,we can take segmented air supply measures,which is adding a secondary air supply with maintaining the temperature of furnace at the same time,to enhance the keystoker coal boiler thermal efficiency by sufficient combustion of coal dust in fuel gas.Ladder application of thermal energyThe rise of coal stoker boiler combustion efficiency becomes more difficult because of the maturity of combustion level,therefore,enhancing the utilization efficiency Of keystoker coal boiler thermal energy in the heat transfer process,realizing the ladder application by considering the using and recovery of high grate energy first,then using the low grate energy,will have goods economic benefit.Waste heat recoveryA lot of high temperature flue gas exists in the operation of coal boilers, if keystoker coal boiler can be recovered to use again, we can achieve the energy conservation in some degree.There are so many ways to reach our aim of energy conservation,to adapt to the development of our society,we must explore them continually.
