Combustion chambers fabricated to the licensor’s design: rolled shell panels in bolted courses on a column and ring-beam base, drilled, trial-assembled, insulated and packed for export in our own works.
A chamber is a stack of rolled courses on a column base. More courses make it taller; more panels to the ring make it wider. The model shows one chamber as we built it. Yours is fabricated to the licensor’s drawings for your duty.

The design is the licensor’s. What we show here is how the steel is made: a column base, a shell of rolled panels in bolted courses, a wind fence and a noise shroud. The model is a typical arrangement, not a client’s drawing. The chambers we built are about 20 m across and 46 m high.

A ring of columns stands at the shell line, from base plates to a bolted splice, tied at the top by a curved ring girder. Each column has a stainless heat shield facing the burners. Holes in heavy profiles need more accuracy than plasma can give, so they are drilled on our Kotec CNC beam line, 3 faces in one pass.
Used here for: The bottom section
Heavy profiles that need precise holes, where plasma cannot do the job: the lower structure and panel borders of a ground flare, and every bolted PEB and multi-storey frame.

The chamber floor is plate on parallel floor beams that span the ring girder, with a framed window over each burner row. Runner pipes at grade feed risers up through the windows. The burner design is the licensor’s.
Used here for: Bottom plate and burner plate
In 2024 we were the only buyer of Deratech’s 20 kW, 12 m laser.

Shown for context: a gas header and valved stage lines running in under the fence to the burner rows, crossed by a grated walkway with a stair at each end.
05 / 11
The lowest courses carry the most load and the noise shroud, so they use the heaviest plate. Each ring is made of curved panels with a bolted flange on every edge.
Used here for: The shell starts

The shell climbs course by course, with the vertical joints staggered from one ring to the next. Plate gets thinner as it climbs. Every panel is cut, rolled and numbered by ring and position.
07 / 11
A rolled angle ring closes each course joint and is bolted all the way round. Studs are welded to the panels and the lining is applied in our works, so panels leave finished.
08 / 11
Straight panels between columns form a many-sided fence round the burners. The lower part is a flat insulated face with access doors; above it, sloping louvres let air in and keep the flame out of sight.
09 / 11
A lined enclosure hung clear of the ground on braced frames, so air still enters below it. Its wall is ribbed plate in panels between posts, and its roof is plate with standing seams, rising to land on the shell.
10 / 11
Every panel is assembled and inspected in our bay so that not one hole mismatches on site. On this project the chamber was trial-assembled four levels at a time; how many levels go up together depends on each project.

A Level 2 coating inspector is on the floor full time; weather is checked and a test run before every batch of paint. The export packing method was developed by our own team.
Used here for: Coated, packed, shipped

The internal structure is erected and checked before the shell goes on: columns, ring girders and every bolted splice.
Four-level trial assembly shown in this project: the shell courses stacked in our bay, with a person for scale.

Fabricated panels standing in a support frame on our shop floor.
Coated and insulated panels travel in export frames we designed ourselves, marked course by course for the rebuild on site.
We fabricate to your drawings and prove the fit in our own bay before anything ships. Open any line for the detail.
