- Burns most low-pressure gaseous fuels, including low-Btu waste gases and hydrogen
- Flame retention at all firing rates with multi-stage stepped-tunnel refractory block design
- Faster bring-up times without temperature override with 40:1 turndown capability
- Maximum application flexibility provided with eight sizes and capacities up to 13,500,000 Btu/h
- On-ratio firing over a broad range of operating conditions
- Alternate refractory block materials for temperatures up to 3000°F gives maximum cost effectiveness
