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.

GROUP mainly produces the following products:

l Waste heat boilers, thermal medium boilers

l Class A1 /A2 pressure vessels

l Reactors, Heat Exchangers & Towers

l Oil tanks/accessories/mixers, alloy steel precision castings

l Four classes of piping supports and hangers used in fired-electric/thermo-electric/nuclear electric power industries and dampers

l Flue gas/air/coal powder duct and its attachments

Boiler ancillaries, water treatment devices and so on

Q: What is the difference between industrial furnaces and boilers?: A boiler is a mechanical device for heating water into hot water or steam by the use of heat from fuel or other sources of energy. The original meaning of a pot is a water container heated by fire. The furnace is the place where the fuel is burned. The boiler includes two parts, the cooker and the furnace.

Q: Should the industrial furnace shell cool down?: The function of furnace shell is beautiful, protective lining, fixed function accessories and so on.

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?: 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: What is industrial furnace masonry?: Pre construction and recording shall be carried out on complex and important parts of industrial furnaces,masonry of all kinds of masonry shall be made with staggered joint masonry.

Q: What's the role of anchor bricks in industrial furnaces?: Anchorage brick is a new type of anchor brick relates to an industrial furnace, in particular to anchor brick of an industrial furnace roof, including column hanging end and the anchor structure, opened in the anchor on the surface of the spacing of the grooves in the anchor on at least one surface is arranged along the length direction ribs is provided with ribs, the ribs of the reinforcement and anchorage tension, tensile and flexural strength was obviously improved, the stress generated in the groove at the bar at the barrier can not continue to transfer, so the anchor brick of this kind of structure is not easy to break.

Q: How many kinds of industrial electric furnaces are there?: This series of electric furnace is made of super light refractory fiber. The electric stove and the temperature control cabinet matching use, the controller may automatically or the manual control electric stove temperature, may press the user request to provide the computer table or the computer control, does the multielement temperature measurement, guarantees the product quality. This series of electric furnaces are periodical operation type electric furnaces.

Q: What are the advantages of a vacuum furnace?: The utility model can completely eliminate the oxidation and decarburization of the workpiece surface in the heating process, and can obtain clean surfaces without deterioration layers. For cutting tools that grind only one side of grinding (such as twist grinding, the surface of the groove surface is exposed to the blade directly), the cutting performance is greatly improved.

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: 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.
