A lined enclosure between the burner and the hot-gas process
A refractory-lined industrial combustion chamber contains the flame and directs hot gas toward the connected process. Its steel shell, refractory lining, burner opening, outlet and monitoring provisions form an integrated supply. Fuel chemistry, temperature cycles and the downstream process determine the lining and interface requirements.
Refractory-lined combustion chamber assemblies for industrial hot-gas generation and thermal post-combustion, including steel enclosure and lining interfaces. Gas-turbine combustors are covered on 8511; complete furnace combustion systems and burner safety sequences on 2975; burner ignition hardware on 3932. An unlined cooled-steel chamber is a separate design choice.

Define the hot-gas duty before choosing the lining
Hans Hennig describes refractory-lined chambers for hot-gas production and thermal post-combustion. Its CKF design offers configurations with or without staged air, flue-gas recirculation and cooling air. State which streams enter the proposed chamber, their composition and conditions, and the required outlet duty. [1]
Hennig notes that refractory selection and lining thickness affect stored heat and the response of the plant control system. Specify the heating and cooling cycles and required process response alongside steady operation. A hot-gas outlet-temperature specification needs its own location and operating conditions; obtain the lining and shell temperature criteria separately. [1]

Map the local exposure around openings and transitions
SBS Refractory Service identifies different combinations of temperature, chemical attack, erosion, cycling and mechanical load within a combustion chamber. Its discussion highlights burner surrounds, constrictions, joints and material transitions as areas needing deliberate design. Locate these features on the proposed chamber drawing. [2]
Give the lining designer the fuel and any entrained solids or corrosive constituents, operating cycle and expected gas-flow path. Agree the hot-face and insulating layers, anchorage, movement joints and connections between material zones. For an existing chamber, provide the position and extent of wear as well as outer-wall temperature records from inspections. [2]
SBS also discusses slag and grate-related zones. Include those conditions where the actual process produces them; a gas-fired hot-gas chamber needs a lining design for its own exposure rather than an assumed grate-furnace arrangement. [2]
03
Identify what the chamber quotation leaves to the site
Hennig’s CKF datasheet lists the steel chamber, brick or fibre lining, staged-air/recirculation muffle, hot-gas outlet and chamber monitoring. It assigns chamber heat insulation and foundation and erection provisions to the customer. Confirm these boundaries in the project quotation. [3]
Ask for the chamber layout, support and thermal-movement requirements, burner mounting, outlet connection, inspection openings and monitoring points. Identify the fuel train, burner controls, insulation, supporting structure and site work included in each contract. Arrange the commissioning and inspection requirements with the chamber and combustion-system suppliers. [3]

Buyer questions
Should one refractory material line the whole chamber?
SBS describes distinct thermal, chemical, erosive and mechanical exposures within the lining. Define the relevant zones with the lining designer and agree materials, anchorage and transitions for those conditions. [2]
Does a refractory-lined chamber quotation include external insulation?
Hennig’s CKF datasheet assigns chamber heat insulation to the customer. Confirm the supplied lining and the site insulation boundary explicitly in the quotation. [3]
Sources and evidence scope
Sources checked 2026-10-18. Hennig’s product page and CKF datasheet describe the chamber configuration and supply boundary. SBS provides a lining-service perspective on local exposure and movement. Product-family heat outputs and outlet temperatures are kept with their published designs; no universal wall rating or fuel-to-air ratio is assigned here.
