Factors affecting the insulation effect of stainless steel chimneys. One of the chimneys is the inner steel plate, followed by the inner lining. The inner lining of the stainless steel insulated chimney is made of 304 or 316 stainless steel. When there is no corrosive medium in the flue gas, the inner lining material is 304 stainless steel. When the flue gas medium contains corrosive gases, such as coal combustion flue gas, heavy oil smoke gas (containing corrosive gases), a double-layer stainless steel chimney should use 316 stainless steel for the inner layer. The outer shell of the stainless steel chimney is made of reinforced concrete, while the inner lining is made of refractory bricks and insulation bricks. Currently, stainless steel plates are used instead of traditional refractory bricks for the chimney lining due to their smooth surface and corrosion resistance. This results in minimal exhaust resistance for double-layer stainless steel chimneys. The height and diameter of the stainless steel chimney can be reduced, significantly reducing its weight and the depth of the pit, thereby greatly lowering costs. The advantages of the stainless steel-lined chimneys are thus quite apparent.

Cautionary Notes for the Use of Stainless Steel Chimneys

Cautionary Notes for Using Stainless Steel Chimneys

The height increase of the smoke flow has a significant impact on the calculation of chimney height. It is essential to choose an uplift formula that is similar to the design conditions. Otherwise, what is a double-layered stainless steel chimney, and enormous errors might occur. Generally speaking, it is advisable to prioritize the formulas recommended in the methods and principles.

2. To prevent smoke from escaping into surrounding buildings, the chimney height must be at least 1.5 to 2.5 times the height of the attached structures; to prevent the chimney from self-cleaning the smoke flow, the smoke flow rate at the chimney outlet must not be less than 1.5 times the average wind speed at that height.

Double-layer stainless steel chimney connection method

1. Clamp connection

This connection method tightly joins two sections of the chimney flue together using two clamps. It is the most commonly used method due to its convenience, simplicity, and flexibility, which allows it to adapt to most installation environments. However, it is important to note that for the thickness of a double-layer stainless steel chimney, you must choose the appropriate size of clamps to avoid loosening during use.
