Multifuel flexibility in biomass boiler combustion is a basic requirement for biomass power plants in China, given the variable nature of the fuel supply for most power plants. 10 years of experience in China have clearly shown that this variability and the quality of fuels most commonly used are the main causes of high levels of boiler corrosion. The most significant impact of fuel-induced corrosion is on fouling, reduction of combustion efficiency and superheater degradation. The results are to be found in lower levels of efficiency, higher maintenance costs and shorter life cycle of the equipment
Such levels of corrosion can be exacerbated due to other factors such as irregular or improper maintenance and operator error in boiler calibration.
DP’s MaxMulti Plus solution is aimed at addressing these problems more effectively, in order to improve boiler availability. Using data gathered over the last 10 years DP experts have developed a new design which also reduces the occurrence and the effects of corrosion DP boiler solutions for the China biomass environment addresses some key design and operation requirements.
Based on the high performing, proven 130 t/h DP boiler, the new design features a variety of modifications. Patented anti corrosion techniques are incorporated within a new boiler configuration; advanced material specifications and integrated, proprietary automated control systems are all used in this enhanced boiler solution to improve operation stability and overall performance
The MaxMulti Plus solution is offered with a maintenance package and an extended 2 year warranty.
