In 2007, Corporation together with Beijing Petroleum University developed a new type of Burner (H-116) at the bottom of Cracking Heater which had been applied on the old Ethylene Cracking Unit in Maoming City successfully.

Ethylene Cracking Heater belongs to Chemical Reaction Heater, fluid will be cracked by catalyst in tubes directly. The cracking of high molecular compound needs high temperature, so, the firebox temperature of Ethylene Cracking Heater is usually more than 1150℃ and tubes shall be heated uniformly. Lots of Burners shall be arranged at the bottom and side walls to meet above requirements. Burners at the bottom often use gas or combination of oil & gas as fuel to provide the 70% of heat productivity. Burners at side walls shall be Flameless Burners and the flame is attached to Walls in round shape.

New types of Burners for Delayed Coking Fired Heater of Coking Unit are designed and manufactured independently by Corporation. They are suitable for Horizontal Tubular Heaters with higher viscosity, lower pressure drop and uniform heating such as Delayed Coking Fired Heater, Viscosity Breaking Heater, and Asphalt Fired Heater etc. Burners of this type have the characteristics of low power, short but strong flame, using classified fuel and high strength of flue gas backflow to effectively reduce the temperature at flame high-temperature area and the generation amount of thermodynamics NOX. Burners of this type can be used under the condition of natural draft of about 70Pa floor negative pressure or forced draft of about 250Pa.

Q: Selection of heat preservation material for industrial furnace: Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.

Q: What is the difference between industrial furnaces and boilers?: Industrial kilns and industrial furnaces are collectively referred to as industrial furnaces. Industrial furnaces mainly refer to devices that heat materials by combustion reactions.

Q: Should the industrial furnace shell cool down?: If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.

Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.

Q: What are the combustion equipments used in industrial boilers?: Main auxiliary equipment for general boilers:1. domestic appliances 2. civilian gas boiler 3. industrial gas furnace.

Q: What is industrial furnace masonry?: Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.

Q: Why does the burner of industrial furnace burn occasionally?: The basic structure of the complete ignition system is the ignition device and flameout protection device. The ignition burner includes an ignition electrode and an igniter (equipped with some external type transformer, voltage transformer) through the above 10kV, the ignition electrode spark ignition of high voltage discharge to ignite gas column.

Q: What are the advantages of a vacuum furnace?: High degree of integration of mechanical and electrical. On the basis of the improvement of temperature measurement and control accuracy, the workpiece movement, air pressure regulation, power adjustment can be programmed in advance, and quenching and tempering are carried out according to the steps.

Q: What is the difference between industrial furnace masonry and ordinary masonry?: Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.

Q: What is the difference in structure between industrial furnace and boiler?: At the same time, the working environment is relatively poor, the structure should be sturdy and durable, the transfer mechanism (generally) to stable and durable low failure rate, the insulation layer must be thick enough and the economy, the steel structure housing materials used to be enough.
