Liquefied fuel gas system for oven

Abstract

The invention relates to a liquefied fuel gas system. One end of a fuel gas main pipeline is connected with liquefied fuel gasification devices. The other end of the gas main pipeline is connected with a diffusion pipeline, and gas branch pipelines are arranged on the fuel gas main pipeline. One or more sets of liquefied fuel gasification devices are connected in parallel. Each set of liquefied fuel gasification device comprises an annular pipeline, wherein at least two liquefied fuel bottles connected through a hose are arranged on the annular pipeline, an outlet of the annular pipeline is connected with gasification equipment through a pipeline, a fuel main ball valve is arranged on a pipeline of the outlet of the annular pipeline, and a fuel gas pressure regulating valve and a pressure gauge are sequentially arranged on an outlet pipeline of the gasification equipment. A diffusion ball valve and a diffusion cap are arranged on the diffusion pipeline. The number of the fuel gas branch pipelines is the same as that of flame paths of a pot-type furnace, and the tail ends of the fuel gas branch pipelines are connected with burners. The liquefied fuel gas system has the advantages that the system can maintain stable gas pressure, the heating rate can be conveniently and accurately controlled, and meanwhile the safety performance is reliable.

Description

technical field [0001] The invention relates to a liquefied gas system, in particular to a liquefied gas system used for starting a pot furnace for calcining petroleum coke. Background technique [0002] At present, the technology of calcination of petroleum coke in tank furnace is favored by the market, and the start-up of the tank furnace has a great influence on the later use effect of the tank furnace and the life of the tank furnace. It is very important to adjust the temperature of the oven according to the set heating curve during the oven process, so the stability of the fuel system used in the oven also has a great influence on the gas pressure and flame shape. At the same time, during the oven drying process, operators are active in the gas area for a long time, which is prone to dangerous accidents due to gas leakage, poisoning or explosion, so the safety of the gas system should be high. [0003] In the past, coal was commonly used as fuel for retort furnaces, b...

At the same time, during the oven drying process, the operator is active in the gas area for a long time, which is prone to dangerous accidents due to gas leakage, poisoning or explosion, so the safety of the gas system should be high

[0003] In the past, coal was commonly used as fuel for tank furnace ovens, but it was gradually eliminated due to poor temperature control accuracy, high labor intensity, and poor environmental protection effects. At present, the most used oven fuel is natural gas.
