Product Description:

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.

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.

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.

GROUP mainly produces the following products:

l  Refinery/chemical furnaces, incinerators, coal (liquid) chemical reformers

Q:What is the difference between industrial furnace masonry and ordinary masonry?
Industrial furnace masonry requirements are relatively high, industrial furnaces of different uses, whether material or masonry process, have strict requirements.
Q:How many kinds of industrial electric furnaces are there?
Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.
Q:Why does the burner of industrial furnace burn occasionally?
The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.
Q:Selection of heat preservation material for industrial furnace
In the neutral and oxidizing atmosphere, the tensile strength, toughness and fiber structure can be maintained for long term use. The temperature is 950-1400 centigrade. Excellent chemical stability; excellent thermal stability; excellent tensile strength; low thermal conductivity; low thermal capacity; excellent sound absorption and noise reduction performance.
Q:What is industrial furnace masonry?
Masonry industrial furnaces refers to complete materials such as brick kilns in construction process.
Q:What are the combustion equipments used in industrial boilers?
The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.
Q:Brief introduction to repair of industrial furnace
The working condition of industrial furnace is very bad. It is affected by high temperature, slag erosion and burden wear. Therefore, its working condition changes quickly and its service life is short.
Q:Should the industrial furnace shell cool down?
Normally, the furnace shell temperature of an industrial furnace is below 50 degrees, so there is no need to cool down.
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.
