Title:
PRODUCTION METHOD OF FUEL BIOMASS, PRODUCTION APPARATUS OF FUEL BIOMASS AND BOILER EQUIPMENT
Document Type and Number:
Japanese Patent JP2018048280
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of fuel biomass that can remove an ash component composed mainly of an alkali metal and an alkaline earth metal and microorganisms in raw material biomass efficiently with low energy and can produce fuel biomass having a low water content and a high calorific value with moisture resistance and antiseptic properties, to provide a production apparatus of fuel biomass and to provide boiler equipment that realizes reduction in operation cost of a boiler, reduction in equipment cost and improvement of combustion efficiency by using the fuel biomass.SOLUTION: The production method of fuel biomass includes a pretreatment step (steps S1 to S4) of hermetically sealing raw material biomass, indirectly heating the same and subjecting the raw material biomass to steam blasting with water contained in the raw material biomass to produce pulverized biomass, a slurrying step (steps S5 to S9) of washing the pulverized biomass with water to produce slurry biomass and a filtration step (step S10) of filtering the slurry biomass to produce solid biomass.SELECTED DRAWING: Figure 4
