Dimensions of a rocket furnace: how to choose the dimensions of a rocket furnace, the optimal ratio of the sizes of the components of a rocket furnace

For those who want to design a home-made oven, you need to know its fundamental dimensions. About how to calculate them and will be discussed in the written article.

How to choose the dimensions of a rocket furnace

It should be understood that all the necessary values will depend on the diameter of the cap, which covers the flame tube, namely: the vertical part. In addition, the drum area also affects the results.

Dimensions of a metal rocket furnace

To begin with, we’ll deal with area indicators of all possible elements.

To determine the cross-section of the riser, you should keep from 5 to 6% of the main indicator.
The flame tube is equal to the riser.
Blown - 0.5 from the furnace.
An external chimney makes up the dimensions, more than 1.5 to 2.

Heights:

The drum is 1.5 times larger than the diameter.
Its coating is equal to 2/3 of the full height.
To determine how much the riser index is, it is worth starting from the viscosity of the flue gases. Of course, the greater the extent, the better. However, do not forget about the special gaps (= 70 millimeters) that should be between the tire and the edge of the product.
The cover of the bed is determined by the drums. If it is 600 mm, then the outcome is from 0.25 of the main diameter. In the case when it is 300 mm, then 0.5D.
The chimney on the outside should be from four meters.

The value of the remaining elements of the system:

Drum coating thickness = 1/3 fraction D.
The length of the fire wire is equal to the height of the riser.
To designate a secondary ash pan, you need to calculate 5% of the original drum volume.

Dimensions of a stone rocket furnace

For a true calculation, it is worth observing a small algorithm:

Having chosen the desired power, remember the burner cross-section: for 25 kW - 120 * 30, 32 kW - 140 * 30, 50 kW - 150 * 30, 80 kW - 200 * 30.
To find the area, the diameter of the inner pipe should be divided into two, squared, and multiplied by the number Pi (3.14). Next round the number.
To determine the external indicator of double radius, it is worth considering the wall thickness, which is approximately 10 millimeters.

What is the optimum size ratio of the components of a rocket furnace

Remember that the length of the portion that is in the horizontal position should be half that of the vertical zone. So that the gases do not fall into the first of them, it is advisable not to make the opposite section short. In addition, in order to maintain a workable system, it is better to adhere to the vertical pipe length parameters of not more than one meter.
