Abstract

The invention provides a liquefied natural gas furnace drying system and a technique. The system comprises a coal pyrolytic gas heating furnace (1), an electronic igniter (2), an auxiliary fire source(3), a furnace drying device (4), a combustion fan (5), a combustion fan frequency conversion regulator (6), a hydraulic natural gas tank car (21), a finned tube steam atomizer (23), a natural gas pressure stabilizing tank (27), a smoke exhaust fan (37), a smoke exhaust fan frequency conversion regulator (38) and a temperature, pressure and flow detection system. The invention aims to: 1) realizesufficient atomization of low-temperature liquefied natural gas, stable gas supply, balance between gas supply and forced purging as well as stable combustion in a forced purging system; 2) solve thetechnical problems of too long flame, too high combustion temperature, difficult control of the furnace drying process and the like of the conventional furnace drying device.

Description

technical field [0001] The invention relates to the technical field of liquefied natural gas ovens, in particular to a liquefied natural gas oven system and a process method. Background technique [0002] In the low-price coal pyrolysis comprehensive utilization project, coal pyrolysis gas (high calorific value coal gas produced by coal pyrolysis furnace) heating furnace and coal pyrolysis furnace are the key facilities of the whole process, coal pyrolysis gas heating furnace and coal pyrolysis Before the furnace is put into production, it is necessary to dry the refractory lining of the furnace body and the refractory lining of the pipeline to remove moisture, and make the lining masonry reach the working temperature (about 1000°C) before putting into normal production. Before the coal pyrolysis gas heating furnace and coal pyrolysis furnace are put into production, there is no gas available for the oven in the factory, and only tanker liquefied natural gas can be used as t...
