【発明の名称】燃料燃焼装置と方法
Document Type and Number:
Japanese Patent JPH0617748
Kind Code:
B2
Abstract:
A fuel burner 2 for burning a fuel such as pulverized coal carried by a fluid, particularly air, has an inner passage for the particulate fuel-carrier medium and an outer passage for a combustion-supporting gas (typically oxygen-enriched air or pure oxygen). The inner passage typically terminates in a nozzle having an orifice therethrough. The inner passage 12 is surrounded by a jacket containing a pressurized fluid. A pressure sensor senses the pressure in the jacket. In the event that abrasive wear of the inner passage causes holes to be formed therein, fluid will pass from the jacket into the inner passage causing a pressure drop in the jacket which is sensed by the pressure sensor. The burner may then be shut down without any hazard having been caused by contact between the pulverized coal and pure oxygen or oxygen-enriched air. The burner may also be used for the autogenous oxidation or thermal cracking of chemicals.
