01.Built-in direct combustion hot blast furnace

Using the built-in burner to directly heat the gas in the flue, the high temperature flue gas generated by combustion and flue gas heating needed directly mixed and exchanged, no related heat loss, high thermal efficiency, small energy consumption, less land area, less overall investment, and low operation cost.

02.External gas (oil) hot blast furnace

The fuel is safely transported to the burner by the fuel supply device, and the air sent by the air supply device is fully burned in the combustion chamber through the burner. The high temperature gas generated is mixed with the cold air in the mixing area, and then the qualified hot flue gas generated. All-steel (steel and mixed) structure, self-cooling and insulation design, the furnace body outer wall temperature is low, no need preheating before furnace operation, low energy consumption, low wear, light weight, small volume, mobile, short installation period, investment saving, simple maintenance.

03.Vertical pulverized coal furnace

A low nitrogen & controlled oxygen industrial hot blast furnace that use powdered coal as fuel to provide high temperature flue gas. Powdered coal is burned in suspension under the air, which has the advantages of rapid combustion, large capacity, high efficiency, wide adaptability, and convenient control and adjustment. With the large-scale flue gas heating capacity, the pulverized coal furnace has great advantages in high temperature combustion, easy control, large-scale and other aspects.

04.Coal fired hot blast furnace

the coal particles below 10mm are sent into the combustion chamber bed layer, and the fluidized combustion formed under the action of high speed air flow sent by allocated plate at the bottom of the furnace.

05.Biomass and multi-purpose hot blast furnace

Burning straw, rice husk, bark, wood chips and other biomass fuel. A furnace can be with multi-purpose (coal fired, gas, fuel oil, biomass burning fuel, etc.), and the furnace has the strength of easy ignition, fast heating, full combustion, high exhaust rate, stable heating, simple operation, convenient maintenance and so on.

06.Reducing atmosphere flue gas furnace

Supporting the "Selecting the weak magnetic iron ore for high speed (fluidized) magnetization roasting" project, providing the hot flue gas to reduce the oxygen through coal burning. The overall project successfully passed the achievement appraisal organized by China Iron and Steel Association, realized the efficient and low cost industrial application of rhemite, limonite and other resources, and opened up a new way for the development and utilization of iron ore.

07.Hot blast furnace for sludge drying

The sludge with a moisture content of more than 70% is dried to about that with a moisture content of 30%. After drying, the sludge is burned through the circulating fluidized bed. The high temperature flue gas produced by the incineration is used for sludge spray drying, making full use of the calorific value of the sludge. It is an investment saving, low cost of efficient energy saving, environmental protection of clean combustion technology, with obvious technical advantages. The production line is composed of sludge drying system, sludge incineration system, sludge collection,storage and transportation system, waste gas and wastewater treatment system, and automatic control system.

08.High-efficiency cylinder cooler

Supporting iron and steel industry bottom furnace directly restore iron production process, 1100℃ material rotates in the rotary cylinder with inclination and guide structure, after spray cooling, from the feed end to the discharge end, the pellet temperature reduced to the 300℃ below. Both ends of the cylinder inlet and discharge are sealed with nitrogen pressure to prevent air entry, providing a closed environment for the cooling of the reduced iron pellet, and preventing the high-temperature pellet from being oxidized. Equipment covers a small area, low consumption, high operation efficiency.
