The Osby P500 is a highly efficient hot water boiler specifically designed for operation with burners firing wood fuels such as pellets, briquettes and chips with up to 30wt.% moisture. The boiler can automatically control between 25%-100% of the design output.

The P500 is of welded steel construction with water jacketed combustion section and three pass flue gas section for optimum heat recovery. The combustion section of the boiler can be supplied with either a welded steel or open floor to suit the burner requirements. The boiler is supplied with burner flange to match the preferred burner and the flange can be positioned in either the front or sides of the boiler as appropriate to the boiler installation. The boiler is supplied insulated with mineral wool and metal clad.

All boiler tubes are fitted with inserts to both increase heat transfer and provide automatic cleaning of the tubes. The boiler tubes are maintained in a clean condition by using a hydraulic system to periodically stroke the inserts in the tubes.

There are also options for supplying the boiler with ash removal screws and flue gas cyclones and a variable speed exhaust gas fan.

The Osby P500 is the result of many years experience in wood fired boiler design. We have focused specifically on high efficiency, low running costs, low emissions, flexible design, simple operation and reliability.
