Abstract

The invention provides a device and method for measuring the hearth temperature of a coal gasification furnace with a double-layer furnace body. In the device provided by the invention, a sensor fixing piece is installed on an inner furnace wall; the ends of a temperature measuring sensor are fixed on the sensor fixing piece after being arranged in an inner hearth; an outer furnace wall flange hole is formed on an outer furnace wall; a flange is connected with the outer furnace wall flange hole; an electric connector is assembled on the flange; after a sensor compensating line which is connected to the tail end of the temperature measuring sensor passes through the outer furnace wall, the positive and negative ends of the sensor compensating line are respectively connected with two plugs; the two plugs are fixed on the electric connector and connected with conducting lines in the electric connector; the temperature change in the inner hearth is converted into electric signals capable of being measured through the temperature measuring sensor and input into the electric connector through the sensor compensating line; and the signals are transmitted to a temperature measuring circuit outside the furnace body through an outgoing line of the electric connector to be measured. The device and method provided by the invention have the advantages of high response speed, high accuracy and long service life, guarantees the reliability and guarantees the stability and accuracy of signal transmission.

Description

technical field [0001] The invention relates to a method for measuring the furnace temperature of a gasification furnace, in particular to a method and a device for measuring the furnace temperature of a coal gasification furnace with a double-layer furnace body. Background technique [0002] The structure of the usual coal gasification furnace is that the furnace body is a single-layer furnace body, and a refractory heat insulation layer is set inside the furnace body. The method of measuring the furnace temperature of this type of coal gasification furnace is to open a temperature measuring hole on the furnace shell, and The temperature measuring sensor is directly inserted into the temperature measuring hole for measurement. The hearth of aerospace pulverized coal gasifier has a double-layer structure, that is, a layer of ring cavity protection is added outside the inner cavity. For the specific structure, please refer to the patent "An Environmentally Friendly Combustibl...
