Title:
SUPERCRITICAL WATER BIOMASS COMBUSTION BOILER
Document Type and Number:
Japanese Patent JP2008292018
Kind Code:
A
Abstract:

To continuously generate high-temperature and high-pressure combustion gas by using, as fuel, all types of biomass having a water content of approximately 90% or smaller regardless of shapes and forms, to generate supercritical water by the direct drive of a gas turbine for power generation or by heat exchange and use the supercritical water for the drive of a steam turbine for power generation, to simplify a device configuration, to collect and effectively use waste heat, to and achieve economy for a distributed power plant.

This combustion boiler device uses a supercritical water oxidative reaction, uses an organic matter with a high water content such as biomass as fuel, and generates high-temperature and high-pressure combustion gas mainly composed of supercritical water. The combustion boiler device has divided operation elements such as "sealing-pressure intensification", "constant pressure-temperature rise", "combustion-temperature rise", "stable combustion" and "discharge-filling", and operates reactors of the respective operation elements. This operation can continuously generate a stable thermal output, eliminate the necessity of the continuous supply of solid fuel such as biomass to a high-temperature and high-pressure system, and achieve batch supply at an easily-supplied temperature and pressure.
