New Lanemark process gas burner installations bring clear gains to dumper truck manufacturing
The latest process gas burner technology from Lanemark Combustion Engineering Ltd . is now helping one of the country ’ s leading manufacturers of construction equipment to benefit from optimised energy usage and minimised emissions . Warwickshire-based Thwaites Ltd ., who provide a wide range of dumper truck designs particularly to the construction industry , have replaced two wellproven existing Lanemark FD5EP-3 burner installations with the company ’ s latest forcedraught gas and air FD5GAP-3 models . The result is a combination of excellent heat control and an anticipated , significant saving in gas usage .
“ The two new burners have been fixed to two separate drying ovens , both of which receive products via an overhead conveyor – one for an epoxy primer preheat facility and the other for a polyurethane top coat drying installation ,” says Jeff Foster , Lanemark ’ s Sale Director who says up to 60 different components for 1 - 10 tonne machines are handled each day .
“ In both cases the burners , which here operate with a Propane gas source , fire through the wall of the oven into a combustion chamber with a recirculating fan then distributing the heat evenly around the oven chamber ,” he adds .
The replacement of the two existing Lanemark burners – both hi / lo units which have delivered reliable performance since 1998 – have allowed Thwaites to gain from the latest designs and technology .
Lanemark ’ s FDGA burners utilise the latest ‘ air pressure lead ’ mono-bloc gas valve technology which is central to ensuring safe and efficient gas / air ratios are always maintained even under variable plant operating conditions . These offer significant benefits compared with alternative fixed gas / air valve linkage control
arrangements while the absence of mechanical linkages between the gas and combustion air control valve and dampers means the need for adjustment or the risk of sticking are avoided .
Thwaites decision to install the two new Lanemark burners was partly based on the company ’ s long term association with the burner manufacturer . Apart from the burners that were replaced meeting operational requirements for more than 20 years , Thwaites had also , more recently , benefited from a further FDGA unit installed on a new standalone oven . “ The performance here meant we had no hesitation in opting for the two additional Lanemark burners for the paint drying facility ,” adds the Paintshop Supervisor .
With the ongoing support of the Lanemark BurnerCare service package – which offers a range of benefits from installation , commissioning and service plans to spare parts supply and rapid engineer call-out , if needed – the new installations at Thwaites are set to deliver reliable , long term process heating efficiency for many years to come . Central to such an important element of the production process , this translates into significant , ongoing peace of mind for the dumper truck manufacturer .
