SINOMEC contracted the technical transformation of the biomass direct-fired boilers, which have been in stable operation since then, incinerating about 500t biomass each day and 150,000t biomass a year.
After the technical transformation, the project can consume about 200,000t - 300,000t straw residuals a year, which is equivalent to about 100,000t - 150,000t of raw coal, greatly saving raw coal, reducing gas emissions and having significant environmental benefits.
