Embodiment Construction

[0010] Embodiment of the present invention: to prevent gasification furnace blow-by gas from causing the shell to heat up, the bottom of the refractory material between the water-cooled wall coil of the gasification chamber and the water-cooled wall coil of the burner seat is fixed and sealed to prevent gasification The gas in the furnace barrel is reversed to prevent the shell from heating up.

[0011] The structure to prevent gasification furnace blow-by from causing the shell to heat up is as follows: figure 1 As shown, it includes a gasification furnace shell 1, on which a gasification chamber water wall coil 2 and a burner seat water wall coil 3 are arranged, and on the gasification chamber water wall coil 2 and a burner A heat-resistant layer 4 is provided between the water-cooled wall coils 3 of the mouth seat, and an annular sealing support 5 is provided at the bottom of the heat-resistant layer 4. The cross-section of the sealing support 5 is a circular tube, and the ...

Abstract

The invention discloses a method for preventing the shell heating caused by air leakage of a gasifier, and a structure thereof. The bottom of a refractory material between a gasification room water cooling wall coiler and a nozzle seat water cooling wall coiler is fixed and sealed to prevent the leakage of a gas in the cylinder of the gasifier in order to avoid the shell heating. The bottom of the refractory material between the gasification room water cooling wall coiler and the nozzle seat water cooling wall coiler is fixed and sealed in the invention, so the flow-out of a high-temperature gas in the cylinder of the gasifier from the refractory material is avoided, and the blow-off of the refractory material by annulus nitrogen of the gasifier is also avoided, thereby the shell heating caused by the leakage of the high-temperature gas in the cylinder of the gasifier is effectively avoided, the production is not influenced, the shut-down caused by the shell heating is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gasification furnaces, in particular to a method and structure for preventing gasification furnace blow-by gas from causing a shell to rise in temperature. Background technique [0002] In recent years, with the development and application of "clean coal gasification technology", entrained bed coal gasification technology with dry feed is one of the most advanced coal gasification technologies in the world today. At present, the dry feed basically adopts the membrane water wall. The gasification chamber water wall coil and the burner seat water wall coil are arranged in the top structure of the burner seat of the gasification furnace, and between the gasification chamber water wall coil and the burner seat water wall coil There is filled refractory material in between, because the filled refractory material inevitably has a certain degree of air permeability, therefore, the high-temperature gas in the ga...
