Regeneration gas heating furnace

The customer needed a regeneration gas heating furnace as part of the gas treatment unit.

According to the technical specifications, cylindrical furnace TsS-1-80-6.00 was suitable, but the customer required non-standard implementation of the project.

Special design solutions:

Furnaces of this design are usually placed outdoors. In this case, the main structures of the furnace had to be placed inside the process workshop building. This solution, in our experience, has no analogs. Its implementation required the development of non-standard algorithms of the furnace emergency protection due to the increasing number of explosive zones (inside the furnace, inside the building, and outside the building) and their combinations.

In accordance with the customer's assignment, the furnace is blown with nitrogen at -50 °C before start-up. This solution is also non-standard. The following measures were taken to maintain the operating capacity of the furnace after the low-temperature blowdown:

• The coil is made of cryogenic steel;
• The furnace seat lining is designed to withstand sudden temperature changes.

The furnace is made in a modular design which allowing to speed up the installation process as much as possible.

The furnace includes a gas analysis system to determine the concentration and amount of NOx, COx, and CH4 emissions in flue gases in all possible modes of furnace operation.
