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.

Boiler ancillaries, water treatment devices and so on

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 the difference between industrial furnaces and boilers?: Hot water or steam generated in the boiler can directly provide necessary energy for industrial production and people's life, but also by the steam power device is converted to mechanical energy, or through the generator converts mechanical energy into electrical energy. Hot water boilers are called hot water boilers. They are mainly used in daily life, and are also used in industrial production. Steam generating boilers are called steam boilers, often referred to as boilers. They are used in thermal power stations, ships, locomotives and industrial and mining enterprises.

Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.

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: 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 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: How to use industrial furnace equipment?: The protection device of the exposed transmission department shall be installed with the correct installation position. The structure is reasonable. The wire rope pulley of the furnace car shall be intact and undamaged. All the pulleys and sprockets on the furnace are in good condition, without defects and flexible in rolling.

Q: Brief introduction to repair of industrial furnace: Although the number of industrial furnaces in general machinery plants is not large, the number of large repairs per year accounts for 16%-20% of the total number of repairs for all equipment, and the large repair costs account for about 18%-25% of the total repair cost of all equipment.

Q: What is an industrial furnace pit?: In twentieth Century 50s, coreless induction furnaces were developed rapidly. Later, electron beam kilns, using electron beams to impact solid fuels, strengthen the surface to heat and fuse materials with high melting point.
