SYSTEM FOR CONTROL OF TEMPERATURE OF BOILER FURNACE SHIELDS Russian patent published in 2006 - IPC F23N5/10 

FIELD: heat power engineering.

SUBSTANCE: system comprises temperature gauges made of thermocouples and interposed between the shield pipes and linings that connect the adjacent shield pipes from the side of the furnace setting. The thermocouple is provided with protecting pipe made of refractory material. One end of the thermocouple projects out of the setting, and the other end projects out of the lining into the space defined by the lining, a part of the outer surface of the adjacent shield pipes, and locking plates that bound it from the side of the furnace and from the faces. The space receives a refractory high-conducting material.

EFFECT: simplified service.
