If your Preston manufacturing operation runs gas-fired process equipment — powder coating ovens, spray booths, bakery ovens, industrial dryers, or any other gas-fired process plant — your process burners need specialist servicing from an engineer who understands combustion, not just central heating.
SMR Gas Maintenance Ltd are Preston's specialist industrial process burner engineers, and in this guide we explain exactly what proper process burner maintenance involves and why it matters to your production, your gas bill, and your compliance.
If you run a manufacturing or production operation in Preston, your gas-fired process burners are among the most critical pieces of equipment on your site.
They are also among the most neglected — because most gas engineers in Preston simply don't have the specialist knowledge, qualifications, or diagnostic equipment to service them properly.
SMR Gas Maintenance Ltd are specialist industrial process burner engineers based in Higher Walton, Preston. We have over 25 years of hands-on experience with gas-fired process equipment across Preston's manufacturing sector — powder coating operations, spray finishing facilities, food production plants, industrial drying operations, and a wide range of other process applications.
In this post we explain what proper process burner maintenance involves, what it costs your business when it goes wrong, and why choosing the right engineer matters.
What is an industrial process burner and why does it need specialist maintenance?An industrial process burner is a gas-fired combustion device that provides controlled, high-temperature heat to a manufacturing or production process. Unlike a commercial boiler — which simply heats water or space to a fixed temperature — a process burner has to deliver precise, consistent heat to a specific application. The temperature requirements, heat delivery characteristics, combustion quality, and safety interlock systems are all more demanding.The most common types of industrial process burner equipment found across Preston's manufacturing sector include:
Each of these applications requires a burner engineer who understands the specific combustion requirements of that process — not just a gas engineer who services commercial boilers.
The real cost of a poorly maintained process burner in PrestonMost Preston manufacturers don't think about their process burners until something goes wrong. That's a costly approach. Here's what poor process burner maintenance actually costs your business:Production downtime.
A process burner that fails mid-production doesn't just cost you the output lost during the breakdown. It costs you the restart time, the product in-process that may be scrapped, the overtime needed to catch up on output, and potentially the customer relationship if you miss a delivery commitment. For a busy Preston powder coating or spray finishing operation, a single day of downtime can cost thousands.Product quality failures.
A process burner running with degraded combustion — dirty electrodes, worn refractory, misaligned combustion head, incorrect air/fuel ratio — doesn't always fail completely. It runs poorly. And poor combustion means inconsistent heat, temperature variation across the process, and product quality issues that may not be immediately obvious but cause reject rates to creep up over time.Wasted gas.
The difference between a process burner running at 72% thermal efficiency and the same burner properly tuned to 91% efficiency is significant — particularly for continuous-operation equipment running through production shifts. For a Preston manufacturer with high-output process equipment, that efficiency gap can represent thousands of pounds in unnecessary gas costs every year.Compliance risk.
Industrial process burner installations are subject to specific legal obligations under the Gas Safety (Installation and Use) Regulations 1998, the Health and Safety at Work Act 1974, and PUWER. An inadequately maintained or improperly certified process burner installation is a compliance liability — and in the event of an incident, the absence of proper service records and gas safety certification will have serious consequences.
What does a professional process burner service involve?A proper process burner service is significantly more involved than a standard commercial boiler service. Here's what SMR Gas Maintenance Ltd carry out on every process burner service across Preston:Full burner strip, inspection, and clean — combustion head, electrodes, nozzles, diffusers, refractory quarls, and all external components inspected, assessed, and cleaned. Worn or damaged components identified and reported.Ignition system testing — spark igniter condition and gap measured, ignition transformer output tested, pilot burner operation verified where fitted, and full ignition sequence timing checked against manufacturer specifications.Flame safeguard and safety interlock testing — trial for ignition timing verified, flame failure response tested, and all associated saf
