Shandong YiranNatural gas heat treatment furnaceAdopting a full fiber structure, it has the characteristics of good thermal insulation performance, light weight, and long service life. It has a high degree of intelligence, simple operation, and easy maintenance. Compared with ordinary refractory bricks, the all fiber natural gas heat treatment furnace can save more than 30% energy and has the characteristics of light weight. Compared with ordinary bricks, it can greatly reduce the amount of steel used.

1. The wall thermal storage combustion system of the gas heat treatment furnace realizes pulse combustion: the thermal storage burner, burner controller, and various automatic control valves form the thermal storage combustion system and the flue gas waste heat recovery combustion system. This new type of combustion system has the characteristics of high export speed, sufficient combustion, significant energy-saving effect, and low nitrogen oxide products. Due to the high flame exit speed, enhanced circulation and convection of gas inside the furnace, the uniformity of furnace temperature and thermal efficiency have been improved, thereby improving heating quality and shortening heating time. The high-speed temperature control burner system for natural gas heat treatment furnaces can achieve automatic control of the entire process, including ignition, combustion capacity adjustment, shutdown alarm, automatic protection, and re ignition.

2. PLC intelligent control system

(1) Natural gas heat treatment furnace temperature control system: The natural gas heat treatment furnace adopts an advanced PLC intelligent control system, and a closed-loop control system composed of well-known temperature measuring components such as Siemens and regenerative burners. The temperature controller interface is connected to the upper computer to form a distributed heat treatment temperature control system, equipped with a high-resolution color screen and CRT operation console. Humanized operation interface, high human-computer interaction friendliness. Adopting advanced fuzzy control principles, it has high accuracy, flexibility, anti-interference and reliability. The temperature control system can automatically calculate, operate, display, store, and achieve full process control of the heat treatment production process curve.

(2) Intelligent control system for furnace pressure: It can set and automatically adjust the furnace pressure to control it at a reasonable value, stabilize the furnace working conditions, and fully utilize the heat of the furnace gas.

(3) Self control system: The combustion air and fuel pipelines required for the combustion system can be set and automatically adjusted through a PLC intelligent control system, so that the combustion air and fuel quantities are controlled at a reasonable ratio, resulting in high combustion efficiency and eliminating the black smoke phenomenon of traditional heat treatment furnaces.

(4) Reliable safety protection system: The Yiran natural gas heat treatment furnace is equipped with temperature, furnace pressure, operation value display of each burner and pipeline parameter, abnormal situation alarm and emergency protection measures on the instrument cabinet.
