INNOVATION A KEY FACTOR IN ONGOING BURNER SUCCESS


From pre-treatment to curing, process heating needs throughout the finishing and surface treatment industry have long been centred on achieving high levels of energy efficiency, excellent control and meeting environmental obligations.


Yet, if these are the watchwords that have underpinned the success of process gas burner specialists Lanemark International – who, since the 1980’s, have supplied oven, tank and air heating solutions across the industry – the company says that a focus on continuous innovation and development is just as important.


The burner options available from Lanemark have always demonstrated its belief in matching specifications to exact customer needs. The FD (forced draught) series of process air heating burner systems, for example, includes the FD-C and FD-E ranges – with or without protective cowl and control box respectively. Both types utilise ‘fixed levels of combustion air’ and can be selected to deliver heat inputs ranging from 40 kW to 880 kW and, in all cases, offer the benefits of turndown rates of up to 30:1 with either ‘High/Low’ or ‘Gas Only Modulating Control’. With a further option to install either in-line or at 90° to the process air flow, and with short flame profiles that are so important for industrial oven design, a vast range of surface treatment application needs can be fulfilled.

Evidence of Lanemark’s commitment to innovation is demonstrated by the recent addition of the FD-C(GA) series to the range which incorporates ‘Gas & Air Modulating Control’ by varying the speed of the combustion air fan. Changes in the combustion air pressure are, in turn, transmitted to a modulating gas/air gas valve train. This combines maximum combustion efficiency with minimum emissions and is ideal for direct fired operations. Again, a choice of heat input is available – from 220 kW to 880 kW – and, as with all Lanemark systems, the burner can operate on either natural or propane gas.


Most recently, this pattern of development has been continued with the company’s TX (tank heating) range with the introduction of the TX80.


“In common with other Lanemark TX systems, the burner is mounted onto the side of a process tank and fires through the wall into a submerged multi-pass heat exchanger.

A combustion air fan, fitted at the outlet of the heat exchanger, exhausts the products of combustion through the system,” explains General Manager Adrian Langford. “The new addition now brings the option of an 8 inch tube system to the table and is able to provide gas input up to 1465 kW.” Significantly, this can remove the previous need to utilise two smaller TX60 burners for processes requiring high levels of heat input – a fact which is of particular note for finishing and surface treatment applications in areas such as the automotive industry.


The TX80 now enhances a range that starts with the 45 kW rated TX15 – which can fire into just a 1½” inch tube system – and includes variants such as the TRX series which brings burner, gas-train and the control system into a single, packaged design. Lanemark has even enhanced its in-house test and demonstration facility by creating a large test tank which can accommodate all TX burner systems in the range – including the new TX80 option.


With all Lanemark oven and tank burner systems, including the company’s range of Midco air replacement heating burner systems, efficiency is fundamental – a maxim which is now at the heart of a second development from the company.


“We are also introducing our latest TxCalc (V5) software which calculates process tank heat losses thereby helping optimise immersion tube heat exchanger arrangements,” continues Adrian Langford. “By selecting the ideal combination of burner, heat exchanger and fan, efficiencies in excess of 80% are typical. This builds on a well-proven design tool which has also been
