1. The annealing furnace is divided into three different types: electric heating, oil heating, and gas heating by different heating methods. They are electric heating annealing furnace, oil-fired annealing furnace, and gas-fired annealing furnace.

3. The annealing furnace is divided into different furnace body structures, such as car-type annealing furnace, pit-type annealing furnace, box-type annealing furnace, and bell-type annealing furnace.

4. Annealing furnaces can also be divided into vacuum annealing furnaces, controlled atmosphere annealing furnaces and annealing furnaces heated in a natural atmosphere.

The annealing furnace is manufactured in a square or round furnace structure. The furnace is equipped with refractory bricks and aluminum silicate fiber composite insulation, or a full fiber insulation furnace lining structure. The workpiece is placed in the furnace, and the furnace is heated by electric heating, or fuel or gas. For the inner workpiece, heat the workpiece to the required annealing process temperature in a natural atmosphere or a protective atmosphere, and after holding it for a period of time, it is cooled naturally or at a controlled rate. Due to the wide variety of annealing furnace series, there are also different operating methods. The trolley-type annealing furnace has an independent loading trolley, which makes the loading and unloading operation easier, and can load large and heavy-duty workpieces. The well-type annealing furnace is suitable for vertical charging of shafts, rods, pipe fittings and other workpieces, and annealing heating Not easily deformed.

The efficiency of biomass boilers is usually higher than 80%. The boiler size is larger, the combustion is more complete, and the boiler efficiency is higher. The highest is 88.3%, which is 15% higher than the average efficiency level of coal-fired boilers.

The ashes produced by the combustion of BMF account for about 1.5% of the fuel. In order to facilitate ash discharge, a spiral slag discharger is installed at the back of the boiler to realize continuous ash discharge. A dust collector is installed in the flue at the tail of the boiler to ensure that the smoke and dust emission meets environmental protection requirements.
