Embodiment Construction
[0019] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] like figure 1 As shown, a liquefied natural gas oven device is a three-layer casing structure installed horizontally, which includes an air center pipe 6, a liquefied natural gas pipe 4, and an air main pipe 14 from the inside to the outside; one end of the three-layer casing structure is the French Lan 1, the other end is a flame nozzle, the nozzle end face 8 of the air center pipe 6 and the nozzle end face 10 of the liquefied natural gas pipe 4 are all located inside the end face of the air main pipe 14, and the nozzle end face 10 of the liquefied natural gas pipe 4 is connected to the end face of the air main pipe 14 The distance is greater than the distance between the end face of the nozzle 8 of the air central pipe 6 and the end face of the air main pipe 14 .

A liquefied natural gas oven device, the device is a horizontally installed three-layer casing structure, from the inside to the outside, an air center pipe, a liquefied natural gas pipe and an air main pipe are sequentially arranged; one end of the air main pipe is a flange, and the other end is a flame The spout, the spout end face of the air central pipe and the spout end face of the LNG pipe are all located inside the air main pipe end face, and the distance between the spout end face of the LNG pipe and the air main pipe end face is greater than the distance between the air central pipe spout end face and the air main pipe end face. The invention is a circular three-channel horizontal roasting device, the front end of the roasting device is an air and liquefied natural gas nozzle, and the nozzle forms a certain angle with the horizontal line, so that the air and liquefied natural gas can be fully mixed and completely burned near the front end of the nozzle, and the horizontal flame and liquefied natural gas can be realized. Short combustion, to prevent the flame from being too long and the temperature being too high to burn the brick lining of the kiln.
Description
technical field [0001] The invention relates to the technical field of liquefied natural gas ovens, in particular to a liquefied natural gas oven device. Background technique [0002] In the low-rank coal pyrolysis comprehensive utilization project, coal pyrolysis gas (high calorific value coal pyrolysis 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 Before the coal pyrolysis 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 were put into production, there was no gas available for the furnace in the factory, and only tanker liquefied natural gas was used as the fuel fo...
