What problems should be paid attention to when using the hot air stove for the first time?

The hot blast stove is used as a heating device, and its use is also periodic. The cold season every year is when the device fully exerts its performance, and it will go to sleep when the chill is over. So what should we pay attention to when we start using it every year?

1. When using each time after dormancy, we should carry out high temperature protection measures for high temperature areas such as combustion chambers and clean rooms, mainly refractory bricks and refractory mud. When used for the first time, the temperature of the furnace should not rise too high or too fast, so as to avoid cracks or even cracks on the surface of the refractory.

2. In terms of coal use, there are differences between the use of the furnace and the furnace that has been used for a while. * Use zui to use some good quality coal. Not only to improve the efficiency of coal combustion, but more importantly, it is necessary to choose the right coal. After calculation, we found that coal with a particle size of 50-60mm burned in a coal-fired hot blast stove. For common fixed grate hot blast stoves, all types of bituminous coal, anthracite and lignite are available.

3. The handling of the chimney, if not used for a long time, is likely to have some problems with the treatment of the flue gas. The general ease of recommendation is the wet desulfurization method, which is also the mainstream method in the industry. In addition, we use the water film dust collector for the flue gas dedusting method.

The difference between the structure of pulverized coal hot blast stove and fuel gas hot blast stove

[1], the heating surface of the furnace is also very different, because it is more complicated, it will not be explained in detail here.

[2], the burner of the fuel hot blast stove must have an oil materializer, while the burner of the gas hot blast stove does not need a materializer.

[3], the fuel hot blast stove uses a burner, and the coal-fired hot blast stove has a combustion method such as a fixed grate, a pulverized coal hot blast stove and a boiling furnace.

[4], the fuel hot blast stove generally does not have a burning device, and the burned exhaust gas is discharged through the chimney. The coal-fired hot blast stove generally has ash hoppers, slag hoppers and other ash removal facilities.

[5], the fuel hot blast stove and the gas hot blast stove have no major difference in terms of the body structure, but the heating surface has been adjusted accordingly due to the different heating values ​​of the fuel. That is, the fuel hot blast stove has a large radiation heating area, while the pulverized coal hot blast stove is designed to have a larger convection heating surface.

[6], fuel hot blast stove, must be equipped with a more complicated oil supply system (especially when burning heavy oil, residual oil), such as fuel tank, oil pump, filter heating pipe, etc., must occupy a certain space, and gas hot blast stove , there is no need to configure the gas storage device. Simply connect the gas pipeline to the gas supply network. Of course, pressure regulators, solenoid valves, buffer valves and other accessories must be installed on the pipeline to ensure the safe operation of the hot stove.
