110t CFB Boiler for India Paper Mill

The paper mill 110 ton CFB boiler exported to India can burn both coal and rice husk. For coal fuel is in short supply in India, but biomass resources is rich. We specially designed the boiler co-combustion coal & rice husk circulating fluidized bed steam boiler for our valued Indian client. Our company has won great praise for the boiler's high efficient, energy saving and long term operation in India.
