CWS Swirl Pre-chamber
Swirl prechamber (furnace) is designed for the effective combustion of liquid fuel, mostly slurry fuel, autonomously or with support fuel. Air slots in a prechamber’s wall form a stable swirl which makes combustion process stable and effective. Liquid fuel has enough time for ignition and full combustion.
- Prechamber is designed to keep optimal number of CWS-torch turnovers inside a pre-chamber what makes both total carbon combustion and transfer (convection) of hot gases into boiler possible.
- Thermal balance of prechamber is designed to keep optimal combustion mode for CWS combustion. Prechamber isolation is chosen to minimize heat losses, quick warming-up period, resistant to quick temperature bursts up to 1300 С° and long-term stable work
- Swirl prechamber is designed to burn liquid fuels, preferably CWS. Prechamber is installed in front or side of a boiler. CWS is sprayed into prechamber where it is preheated and burned. Combustion products (hot gases) further moved to a boiler.
- Boiler which is equipped with a prechamber can burn both CWS and other fuels: diesel of heavy fuel oil (depending on boiler type)
- There is a range of prechambers produced between 0.8 and 11MW
- Connection to boiler is made individually
Prechamber consists of
- Prechamber consists of door with a diesel/gas burner, prechamber body, blower, CWS-nozzle, control system.
- Front door has mounting holes for mounting mazut and/or diesel burner required for initial preheating. Additionally it has eye holes for visual control.
- Prechamber body is a horizontal or vertical cylinder equipped with thermo-sensors, CWS nozzle, secondary air input and secondary air slots for creating a swirl. Body is isolated with fireclay bricks
- Blower creates a secondary air flow which makes a swirl inside a prechamber
- Control system makes possible to vary parameters of combustion depending on fuel characteristics
