FEATURE BOILERS, BURNERS & CONTROLS SWITCHING BOILER FUEL TO LPG CUTS CO2 EMISSIONS
A premium dry pet food manufacturer has saved in excess of £50,000 and more than halved its CO2 emissions since converting its boiler fuel from oil to liquefied petroleum gas (LPG) from Calor. C&D Foods’ site in Larkshall, Norfolk produces approximately 20,000 tonnes of dry pet food every year, requiring a significant amount of fuel to power its manufacturing processes. Situated off the mains gas grid, the company has partnered with Calor for the past 20 years using LPG to fuel a collection of large on- site industrial dryers that reduce the moisture content of the dry pet food once it has been extruded. Having established a strong relationship as C&D Foods’ fuel partner of choice Calor approached the business in the summer of 2014 with a plan to dramatically improve its existing oil boiler efficiency and lower its carbon output. “Calor removed the existing large oil tanks and installed six 4,000 litre LPG tanks and a vaporiser that can give us extra power when needed,” explains general manager Ian Harridge. “Calor then supplied and installed a packaged gas burner to allow us to modify its original oil burner.” The ability to install a packaged gas burner meant the entire boiler system did
LPG’s reduced CO2 impact compared to
oil was a critical reason behind the site’s decision to fully embrace gas for its processes as the site continues to work toward the Carbon Trust Standard. LPG is currently the lowest off-mains carbon emitting fuel available on the market: 20% less CO2 per kWh than oil. Since switching to LPG C&D Foods has reduced its CO2 emissions by 52%. The reduced overhead costs and improved operational efficiencies achieved with LPG was a key driver for C&D Foods, resulting in financial savings of more than £50,000. Each LPG tank is fitted with Calor’s
not have to be replaced which would have incurred substantial costs. “We chose Calor because they’re market
leader with the best coverage for off- mains sites. In addition, the proposal that they put forward to assist with the installation of the new equipment was excellent, minimising downtime or additional costs. Calor worked around times when the plant did not need to run which included some weekends. The installation went through with no real interruption to the business.”
Each LPG tank is fitted with Calor’s intelligent automatic top-up technology, alerting the supplier when fuel is low
intelligent automatic top-up technology which alerts the supplier when a tank is low on fuel. This ensures C&D Foods has a constant supply of fuel, guaranteeing a tank never runs short. “The service provided by Calor has been second-to-none,” concludes Harridge. “They managed the whole project for us from fitting the new foundations for the equipment to connecting the boiler and commissioning. Based on our experiences I would have no hesitation in recommending Calor to other businesses.”

MEETING LEGAL OBLIGATIONS FOR BOILERS AND STEAM GENERATORS
CEA has arranged two seminars for BG04, I-GAS & MCPD at the Cambridge Belfry Hotel, Cambridge on Wednesday 7 September 2016 and Telford Hotel and Golf Resort (near Iron Bridge), Telford, Wednesday 12 October 2016. These events provide the opportunity to understand and discuss your role and responsibilities for these three very important areas of industrial activity and to help you comply with legal obligations and meet with industrial best practice.
CONFERENCE PROGRAMME Industrial Boiler Water Treatment (BG04)
for shell boilers both steam and hot water, coil boilers and steam generators up to 32 Bar: A simple industrial guide developed to help operators and managers responsible for boiler water treatment and who do not have any chemistry background. Most boiler incidents are as a result of badly managed or poorly implemented boiler water treatment. Hard copy of

affected by Brexit. The CEA and ICOM Energy Association have joined forces to produce an easy- to-follow Industrial Water Treatment Guide for steam and hot water boiler systems. Designed for use by non-specialists through the use of straightforward language the guide will become an integral component of the training courses run by the CEA for operators and managers of industrial and commercial boiler plant. Designated BG04, the guide was launched at the CEA’s conference in July to an audience of primarily plant managers and engineers. It was well-received and acknowledged
as providing an invaluable insight into the responsibilities of managing commercial and industrial boiler plant.
