The integrally built PFT® Heater and Heat Exchanger insures the compatibility between the boiler, heat exchanger, and controls required for successful operation.
Safety is the paramount consideration in the PFT® Heater and Heat Exchanger design. The flame safeguard system operates throughout the boiler firing sequence guaranteeing safe boiler performance. The induced draft fan maintains a negative pressure on the firing chamber, eliminating the possibility of dangerous gases leaking to the surrounding area. The configuration permits the burner to operate at lower digester gas pressures, eliminating the need for gas booster pumps and optimizing the use of all available digester gas.
- All fired surfaces transfer heat to the boiler water.
- The water back will last the life of the boiler resulting in a substantial savings in maintenance and a reduction in downtime.
- Heat exchanger designed for durability and ease of maintenance.
- Return bends made of cast iron construction to insure long life.
- Tubes held in place by gaskets made of cast iron following rings.
- Multiple gasket arrangement insures early detection of gasket failure and eliminates the possibility of waste solids or water fouling the interior of the heat exchanger frame.
