Recently, Zhenghe Group’s coal water slurry fired boiler renovation project received 300,000 yuan ($48,887) in funding from the Guangrao government.
The project applies suspension-fluidized combustion technology and utilizes cheap water slurry in place of raw coal. The change not only raises the boiler’s efficiency, but also reduces smoke and ash. It went into operation in Nov 2011 and consumes 0.119 tons of standard coals per ton of steam, 0.046 tons less than before. It will save 11,892 tons of coal a year.
