Octagon - Gas Burners and Heaters for Crops
From Gas Burners
The ideal heat source for drying onions, flower bulbs, hops and all types of grain. Octagon modulating gas heaters are designed for use with either axial or centrifugal fan units. Heater units are available with outputs ranging from 250,000 Btu/hr (75k.W)up to 4,000,000 Btu/hr (1000k.W.). For centrifugal fans, single heaters with heat outputs up to 4 000 000 Btu/hr are available. The burner head is mounted inside a steel casing and is supported by a steel framework. For axial fans, the total heat output is split between the number of fans attachedtothemainduct.Eachburnerheadismountedinside agalvanisedsteelcasing, which is the same diameter as the fan casing. The linear burner head is designed to burn cleanly in high volumes of air, whilst the modulating valve offers up to 80 stages of heat to ensure an accurate control of temperature and economy of operation.
- First & second stage regulators,
- Auto pilot start for flame U.V. sensing and control
- Twin main flame solenoids
- The modulating valve which controls the heat output through the linear burner head, which has a turn down ratio of 25:1.
For a 1,000,000 Btu/hr. burner the maximum heat is 1,000,000 Btu/hr whilst the minimum flame size produces 40,000 Btu/hr.
Protective devices fitted are I) Overheat, II) Airswitch, III) Flame failure, IV) Fan failure, V) Power failure.
