Abstract: Aiming at the problem of incomplete coal combustion and generally low thermal efficiency in actual operation of coalfired
chain boilers, this paper developed the infrared energy-saving patented technology by studying the inherent characteristics of
coal seam combustion and furnace wall material characteristics of chain boilers. This technology uses infrared energy-saving
furnace linings to strengthen coal seam fire, high-performance heat insulating material and optimized furnace arch structure to
improve heat radiation and heat preservation performance to promote ignition and combustion of new coal seams, reduce heat loss
and effectively improve coal utilization efficiency. Practical applications show that the technological transformation has achieved
significant energy-saving effects.
