Osby Parca GTP
Boiler For Oil/Gas, 0.75 - 12MW
Self-circulating fire tube boiler
The Osby Parca GTP has a cylindrical furnace and a tube equipped convection section where the flue gases 
pass in two strokes withoutnbturbulators.
The boiler is of welded steel and the the furnace, the turning chamber and the convection tubes are completely water cooled. The boiler is selfcirculating, this treat provides an even water temperature throughout the boiler.
This boiler is based on a very reliable design and is primarily intended for firing oil or gas but it can also be adapted for firing modern fuels like bio oil, pellets and wood chips.
Cleaning of the flue gas tubes is carried out from the front through a large insulated door. Cleaning during operation can be performed using for example steam or compressed air.
This boiler type is also available as a steam boiler, GTP.

Water temperature
The standard water temperature is max. 165 r 204 °C. The return water temperature is min. 60 °C at Δt of 30 °C at nominal output.
Water flow
The boiler has a connection for a thermal flow switch. There is no demand for minimum flow if a thermal flow switch is installed. An electronical ow switch can also be used. Formula for calculating minimum flow: m3 / h = output (kW)/ 464
