Problems solved by technology

[0007] The above-mentioned disclosed regenerative combustion devices or systems can only preheat air or gas, or both air and gas at the same time, which play a positive role in recovering waste heat of flue gas and improving fuel combustion efficiency, but cannot directly ignite gas. Therefore, under some process conditions that require intermittent ignition and combustion, the ignition function of the burner needs to be started many times, which will easily cause burner loss and affect the service life of the burner

Abstract

The invention discloses a heat-storing combustion apparatus and a biomass gas heating system, which comprises a heat storage chamber and combustor bodies, wherein a plurality of heat storage body processing holes are arranged in the heat storage chamber; combustor nozzle holes are arranged between the plurality of heat storage body processing holes; the heat storage body processing holes and the combustor nozzle holes are radially separated rather than communicated; ceramic heat storage bodies are placed in the heat storage body processing holes; the combustor bodies are placed in the combustor nozzle holes; and external combustion-supporting medium is heated by the heat storage bodies and mixed with a biomass flammable gas entering from the combustor nozzle holes at the end of the heat-storing combustion apparatus, so that the biomass flammable gas can combust. In the invention, the high-temperature combustion product and low-temperature combustion-supporting medium perform indirect heat exchange through the heat storage bodies in turn, so the utilization rate of combustion gas heat is improved and the combustion stability of the combustion gas is ensured.

Description

technical field [0001] The present invention relates to a combustion device for a biomass gas heating system and a biomass gas heating system using the combustion device; more specifically, the present invention relates to a regenerative combustion device and a biomass combustion device using the combustion device Gas heating system. Background technique [0002] Regenerative combustion technology has multiple advantages such as high efficiency, energy saving and low pollution emission. The high-efficiency regenerative technology was first developed in the 1980s by the British Hot Work Company and British Gas Company. It was called the rcb burner (regenerative ceramic burner) at that time. After 1993, due to Japan's breakthrough in high-temperature-resistant heat storage materials, combined with the improvement of combustion high-speed switching control technology, and the application of low-NOx combustion technology, high-efficiency regenerative combustion technology has c...
