Coal-fired heat conduction oil boiler

Abstract

The invention relates to the technical field of industrial heat conduction, and discloses a coal-fired heat conduction oil boiler. The boiler comprises a boiler tube, a cooling chamber is fixedly connected to one side of the boiler tube, an electromagnetic switch is arranged in the middle of the connection of the boiler tube and the cooling chamber, a heat conduction oil circulating device is fixedly connected to the other side of the cooling chamber, a steam starting device is movably installed on the other side of the heat conduction oil circulating device, an induced draft fan base is fixedly installed on the other side of the steam starting device, and a water pipe used for spraying and cooling is arranged above the induced draft fan base. Steam generated by cooling of the induced draft fan base through the water pipe drives the steam starting device, the heat conduction oil circulating device is driven by turning of a turning device during emergency power failure, the electromagnetic switch is turned on without electricity, so that high-temperature heat conduction oil in the boiler tube flows into the cooling chamber more quickly, and the problems of boiler tube deformation and even fire caused by stagnation of high-temperature heat conduction oil in the boiler tube in a power failure state are solved.

Description

technical field [0001] The invention relates to the technical field of industrial heat conduction, in particular to a coal-fired heat conduction oil boiler. Background technique [0002] Coal-fired heat-conducting oil boiler is a kind of equipment that uses heat-conducting oil as the intermediate medium for industrial heat exchange. It uses a circulating oil pump to force the medium to perform liquid-phase circulation to transfer heat to the heat-consuming equipment and then return to the heating furnace for reheating. However, the existing Coal-fired heat-conducting oil boilers still have some defects: first, the temperature of the heat-conducting oil in the furnace tube is as high as 300°C, and the circulating oil pump will stop working in case of power failure or maintenance in an emergency, causing the high-temperature heat-conducting oil to stagnate in the furnace tube. The high temperature of the furnace itself and the high temperature of the heat transfer oil will cau...
