Energy Savings for Tata Steel Following Spooner Anguil RTO Installation

What the average person may not realise is that there are two types of carbon footprint, a primary and secondary. The primary footprint is a measure of our direct emissions of CO2from the burning of fossil fuels including domestic energy consumption and transportation, e.g. car and plane. The secondary footprintis a measure of indirect CO2emissions from the whole lifecycle of products we use, those associated with their manufacturing and eventual breakdown. Improving the energy efficiency of industry both safeguards jobs and reduces our secondary carbon footprint. Tata Steel (formerly Corus) turned to Spooner Industries of Ilkley, West Yokshire, to help them realise an energy saving project which aimed to reduce the gas consumption by 45%. The colour coat line, based at Tata Steel in Shotton, produces painted steel strip where the paint is applied and dried in an oven system. The finished materials are used in the construction industry, for example the new Spooner facility is finished almost entirely in painted steel, as well as being used for household appliances such as refridgerators, washing machines and dishwashers. In partnership with American company, Anguil Environmental Systems, Spooner provided Tata Steel with a Regenerative Thermal Oxidiser (RTO) which destroys the harmful solvents evaporated in the process and recovers over 85% of the energy required to destroy the solvents. Since the installation of the Spooner Anguil oxidiser, Tata Steel is on course to save 60% in the gas use, over £1million a year, and reduce CO2 emissions on the plant by over 1 tonne every hour, nearly 8,000 tonnes per year. In addition to the oxidiser, a secondary heat exchanger recovers energy by pre heating the air going into the ovens. The investment from Tata Steel was considerable, the existing system was 30 years old, and the ovens had to be bought up to the current standards. A new computerized control system was installed with dedicated safety systems. This system communicates with the central system at Tata Steel and sets up the ovens correctly for each product. Spooner Industries manufacture bespoke ovens, dryers and pollution control equipment for a variety of markets worldwide. The company has been based in Ilkley since 1951 and currently has over 100 employees. Catering for a range of industries including paper, converting, metals and food, Spooner is continuously developing new technologies and solutions in the in-house testing and R&D facilities to remain at the forefront of the industry. In addition to the Ilkley headquarters, the company has a network of agents and representatives across the globe, providing a local point of contact for almost every client, wherever their location.
