GBS

Features

1. Low O₂　Wide flamestability limits are achieved,
　performing low O₂ operation in the restricted furnace.

2. Low NOx
　The concept of staged combustion is applied in center gun type nozzle,
　which meets NOx reduction requirements.

3. Perfect Performance
　Designed to avoid flame impingement, enhanced wide turn down ratio.

4. Simple Combustion Control
　Flame modulation can be achieved by 2 combustion modulation levers fitted to
　front plate, which ensures full control of air/fuel mixing is maintained.

5. Convenient Operation
　Designed to operate boiler without separate auxiliary panel since control
　can be performed by one control system.
