Gas heat exchangers. Buy a gas air heat exchanger

The heat exchangers Gas-gas and Gas-air are usually used to heat the incoming streams of air by flue gases, steam or similar medium.

Heated air or gas can be used to increase efficiency of production processes or to maintain temperatures in premises.

Design advantages

High output when heating large air or gas volumes

Can operate at high temperatures of gas medium

Compact design and lower weight make installations possible where conventional heat exchangers can not fit

Design of Ribbed plate recuperators

The ribbed plate recuperators are composed of stainless steel plates joined together in a cross way. So, in one layer the medium is passed through in longitudinal direction and in the next layer — in transverse direction.

The methods of plates joining:

Оребренная панель совмещается с такой же панелью (крышкой)

1. A ribbed plate is covered with a lid without ribs. The next ribbed plate is placed on top of the lid ribs-down in a cross way.

Оребренная панель закрывается гладкой крышкой

2. A ribbed plate with ribs-up is joined with a another ribbed plate ribs-down.

Панели соединяются между собой оребренной и гладкой стороной

3. Two ribbed plates with ribs-up are joined in a cross way.

In the first two options transverse spacers are established between the elements according to the principle of the third option. The motion pattern of two medium is cross flow, the heated air moves transversely to the direction of hot gases. Power of the heat exchanger depends on the temperatures of the medium, the number of modules and the method of panel connection.

The elements are assembled (welded) into a module:

For the first two variants of the assembly, elements are welded together with transverse spacers.
For the third version of the assembly package is welded forming cross-arranged panels;
In all cases, two cross-channels for the heated and heating medium are formed.
