Smoke Gas Ducts for Boilers - Efficient Airflow Management

Gas-air pipelines connect fans and smoke exhausters with boilers. Air pipelines made of steel sheets up to 2 5 mm thick and gas pipelines made of steel sheets up to 5 mm thick have, as a rule, a rectangular cross-section. The outer surface of gas and air pipelines after air heaters is covered with thermal insulation. The inner surface of gas-air pipelines should be without ledges and ledges, as they create additional resistance and contribute to the accumulation of coal dust, spontaneous ignition of which can cause an explosion and accident.
