| The LND/Series gas, liquid fuel, and combination gas/liquid fuel burner is a forced draft packaged burner system. A backward curved aluminum impeller mounted in a machined housing provides combustion air for various furnace pressures or high altitude applications. The air housing is hinged for convenient inspection or service of the firing head components. |
| Liquid fuel firing features, Industrial Combustion's low pressure air atomizing design. A metering unit, rotary vane air compressor, and air atomizing nozzle are integral parts of the system. The positive displacement oil metering unit is not affected by changes in oil temperature or viscosity. |
| Efficient gas combustion is attainde by introducing gas through ports ahead of the diffuser providing superior mixing of gas and air. Excellent flame retention is assured at all firing rates. |
| Flue gas recirculation (FGR) is drawn through the burner blower assembly properly sized for the required NOx emission levels. An FGR control valve is positioned by the FGR system to provide FGR at all firing rates. An FGR shutoff valve is placed in the FGR line as part of a safety system. This shutoff valve prevents combustible gases from being drawn into the boiler furnace prior to pilot and main flame ingition. Proper operation of this system is proven by three (3) electrical saftey interlocks. The system is equipped with ANSI flanges to allow easy installation into the FGR piping |
| High turndown capability on all fuels assures smooth starts and response to wide loade demands. Maximum effiency is achieved throughout the firing range. Convenient control switches permit selection of fixed rate or fully modulation operation. |
| A simple flip of a switch, on a Gas/Oil combinationburner, allows you to fire on one fuel or the other. No burner modifications or readjustments are required when changing fuels. | Listed by Underwriter Laboratory, CSD-1, I.RI., F.M., C.S.A. and other regulator agency control options are available. Every I.C. burner is assembled, wired, and tested at the factory. Compressor modules and main gas train components are shipped loose. |
