Solid fuel cooking

Both wood-fired and charcoal-fired equipment are classed as Solid Fuel Appliances (SFA). However distinct design considerations are necessary when dealing with one as opposed to the other. Considering these differences is crucial to delivering a safe and effective system.

In addition, SFA systems are now considered as Local Exhaust Ventilation (LEV). This means that they are to be used, maintained and monitored under LEV guide HSG 258 in addition to its designation as a kitchen ventilation system under DW/172, TR/19 and DW/144.

The solid flue extract includes:

CO monitor and alarm with automatic ramping in case of spillage.
Electronically Commutated (EC) fan (High efficiency fan).
A specially designed jet pump to draw combusted gas and solids away from the ovens. This allows the fan to be placed outside of the air stream which can reach temperatures of 450 degrees C.
Flue manufactured from 0.9mm SS ducting, cladded with 0.9mm outer galvanised skin with insulation between them.
Access doors positioned to allow for very regular cleaning, all doors fabricated by welding and bolted. Appropriate high temperature seals used on doors.
