A coal-fired heat transfer oil boiler

Abstract

The invention relates to the technical field of industrial heat conduction, and discloses a coal-fired heat conduction oil boiler, which includes a furnace tube, one side of the furnace tube is fixedly connected with a cooling chamber, and the middle of the connection between the furnace tube and the cooling chamber is provided An electromagnetic switch, the other side of the cooling chamber is fixedly connected with a heat conduction oil circulation device, the other side of the heat conduction oil circulation device is movably installed with a steam starting device, and the other side of the steam starting device is fixedly installed with an induced draft fan Seat, the top of the induced draft fan seat is provided with a water pipe for spray cooling. In the invention, the water vapor generated by cooling the induced draft fan base through the water pipe drives the steam starting device. During an emergency power failure, the direction changing device is used to change the direction to drive the heat transfer oil circulation device, and the electromagnetic switch is opened without electricity, so that the high temperature heat transfer oil in the furnace tube is realized. It flows into the cooling chamber faster, which solves the problem that the high-temperature heat transfer oil stagnates in the furnace tube in the power failure state, causing deformation of the furnace tube and even causing a fire.

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...
