Design series of waste heat radiation-convection boilers

The radiation-convection boilers are multi-path and have a U-shaped design. The boiler operation is boosted by auxiliary heating if the utilisation gas temperature is insufficient for steam production.

The primary purpose for which this type of boilers has been designed is the increasing tendency to destroy high-temperature contaminated gases (~1200°С).

The solution to the problem is a three-path system of gas movement and use of gas-tight membrane panels. Thanks to this system as well, the boilers are capable of obtaining steam with energy generation parameters and then using it in a steam turbine to produce electricity. The burner devices used in the boilers make it possible to burn attendant petroleum gases and gases produced in crude oil processing with a wide range of calorific capacities.

This series of waste heat boilers has a large number of application options:

  • production of heat and electricity for industrial purposes from combusting attendant petroleum gas in facilities extracting and producing crude oil;
  • combustion and utilisation of heating gases (gases from crude oil processing);
  • utilisation of heat in process gases in production plants for catalytic cracking or catalytic reforming for superheated steam production;
  •  cooling of waste gases from afterburning furnaces in facilities for petroleum bitumen production.

The boilers are supplied in transport units, parts, components. The unit design reduces the transport and installation costs, and increases maintenance and repair ability. Waste boilers are equipped with platforms and ladders for maintenance and repairs, necessary closing and control fittings, safety valves, accessories, inspection and metering instruments.
