steam boiler

High efficiency combustion ( up to 85% ) Exactly temperature controllingNo local overheat or overpressurePrecise manufactured tube bundlesMinimal heat loss because of high effective insulationRearward wall of combustion chamber is partly cooled by thermal oil thereby no tension cracks of bricksFront door on hinges thereby easy possibility of cleaning to pressure the high eficiency. Clod start thermostat reduces burner capacity till the minimum viscosity of Thermal oil is reached. Combustion is blocked till the pump running properly. Flow monitoring by type tested differential pressure system. If the minimum flow falls short the burner stops at once. Safety thermostat controls max. supply temperature and stop the burner in case of over temperature. Flue gas thermostat switches off the burner if the allowed temperature will exceed. All the safety appliances additional sounds optical and acoustic alarm. The source of error is shown at the control cabinet. All appreciated safety devices are type tested according to German standard Din 4754 and VDI 3033
