according to different minerals, different furnaces can be designed here: nickel iron furnace, manganese furnace, copper melting furnace, chrome ore furnace, Magnetite furnace etc., including inlet system, feeding system, roof system, front slagging and tapping system, gas system, power system, cast iron machine, hot blast furnace, thermal instrumentation system. Our furnaces have advantages of high yield, low coke rate, no nodulation, and easy operation. With the top advanced technology, every procedure is the optimal scheme after repeated screening, which makes things more reasonable.
What is Blast Furnace Gas
Blast furnace gas is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value, about 93 BTU/cubic foot, because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable. The rest is mostly carbon monoxide, which has a fairly low heating value already and some (2-4%) hydrogen. It is commonly used as a fuel within the steel works, but it can be used in boilers and power plants equipped to burn it. It may be combined with natural gas or coke oven gas before combustion or a flame support with richer gas or oil is provided to sustain combustion. Particulate matter is removed so that it can be burned more cleanly.
Blast furnace gas is generally used to as the raw materials of steam - gas-fired combined cycle power generation. Blast furnace gas fired boiler designed and manufactured in ZG Boiler is suitable for iron, steel, and it is also the best choice of the nation to sustainable development and green economy.
Blast Furnace Gas Fired Boiler Structure
1. Using "� " Type Arrangement
With whole structure "� " type arrangement, the blast furnace or coke oven gas fired boiler adopts front suspending back supporting, plumbing systems, superheater and other suspended from the roof on the boiler, economizer, air preheater, etc. are arranged at the rear steel shelves, air preheater can be pulled out from the back, which are easy to maintain.
2. Square Chamber Design
The furnace is design as square, and the burner is arranged in the corners, using the four corners of the vortex burner ignition, also has a higher temperature of the hot air, combustion gas required to ensure that the temperature field and the aerodynamic conditions not only to ensure adequate fuel gas combustion, but also to prevent the fuel gas and air mixture within the burner.
3. Multiple Security Devices
In addition to conventional protection device, the boiler is also equipped with automatic ignition device, flame monitoring device, flame protection device and supply device which automatically cut off the gas when the gas pressure is lower than a certain value and other safety devices
High vacuum aluminum brazing furnace is applied for vacuum brazing of materials like heat exchanger, air condition evaporator, condenser, radar grid antenna, wave-guide tube, etc.
Function
1. Reduce the hardness of steel pipes, improve the plasticity, to facilitate cutting machining and cold deformation.
2. Fine grains and homogeneous steel organization and composition, to improve the performance of steel, also to make preparation for the heat treatment.
3. Remove the residual internal stress in steel, to prevent deformation and cracking.
Feature
1. No need pre-heating. Comparing traditional black annealing furnace, it only takes 10-15 minutes to reach the exact temperature.
2. No need re-straightening. UsingÃ? rotary tube delivering structure, there is only tiny deformation after heat treatment.Â
3. Automatic uploading tubes, with strict docking of front and rear tube's end.
4. Fully automatic running, saving labor cost.
Large diameter welded pipe black annealing machine is a special machine for heating the steel pipe to solution temperature and then cool it to room temperature. This machine adopts the advanced induction heating power supply, the new type DSP+IGBT power supply. It uses IGBT inverter, DSP precision control, air-cooling structure( water cooling for induction coil), reduce the loss of system. It has perfect self-protection and self diagnostic function, saves 15% energy comparing with the similar product. It is the first machine that could annealing such large stainless steel welding pipes.
Process Flow
Continious type stainless steel pipe bright annealing furnace can heat the stainless steel welded pipeto 1050 C then cool it to the temperature lower than 100 C under the protection of hydrogen.The heating power supply of the intermediate ferquency induction is the newest DSP+IGBT structure.With DSP digital control system,there are self protection and self diagnostic functions.With small volume,it heats pipes rapidly and efficiently with energy-saving and low-waste features.The especially developed inducer designed according to the features of stainless steel can save 15%-20% energy in contrast of other products of the same class.Using hydrongen as of gas every minute.

This machine is suitable for all kinds of agricultural and forestry biomass charring making. For example, wood shavings, sawdust, wood chip, rice husk, cotton stalk, crop straw, bean curd, etc
Principle
First, the biomass material is ignited in the gasifier. The flue gas produced by burning after spraying, cooling, purification process, it produces the pure combustible gas (carbon monoxide, methane, ethane, etc.).As the early stage of the carbonization of heat source, through the early warming of the carbonized, to feed the material when the heat reaches the special temperature. The combustible gas that carbonation process of flue gas by spraying, cooling, purification process into the burned secondary. According to this method of circulation, sufficient to achieve a self-sufficient, then achieve the effect of energy-saving. The flue gas through purification, to reach the environment production and flue gas emissions-free. Which is reached to the standards of waste gas emptying.

Here are some of the reasons why induction furnaces ideal for melting of copper:
Power Regimes:
Induction melting furnaces tend to be more flexible when it comes to alloying. These furnaces can be easily shut off any time the plant or factory closes, and relining is fairly quick and simple. They also tend to be more economical in terms of energy consumption, and they usually have a longer refractory lifetime. In the Induction furnace melting rate is very fast and large quantity of the metal can melt very quickly.
Reliability:
When it comes to melting copper, a copper furnace based on induction is far more reliable than most others. Due to latest IGBT technology and standard built up the maintenance of furnace is almost nil, manufacturers can get the most out of this type of furnace without the need for any repairs.
Cleanliness:
It''s well known that induction furnaces emit far less pollutants than other types of furnaces. Not only does this mean that you are protecting your employees from breathing in harmful substances, but having a clean atmosphere will also prevent any additional oxidation of the copper.
Energy Efficiency:
A recent study noted that today''s modern induction furnaces can achieve higher electrical efficiency levels. That means less of a negative impact on the environment, and it means you won''t be wasting more on energy costs.
