Indirect heating system for burning solid combustible particle e.g. coal, has dust collector collecting ultra fine particles and feeding particles to furnace through specific pipe line and burning particles by specific burner

摘要

The system has a grinder crushing a solid combustible particle e.g. coal into fine particles. The ultra fine particles are collected by a dust collector (10) and stored in an intermediate storage bin (60). The fine particles are proportioned in a feeding device and mixed with correct portion of hot air. The particle and air mixture is fed to a furnace through a specific pipeline (52) and burnt by a specific burner (71).
