With the tightening of NOx regulations there are clear advantages to utilising the latest technologies to reduce emissions. Bernard Dawson of Riello Burners considers options such as flue gas recirculation in pressure jet burners.

The UK’s schools and educational facilities are regularly experiencing problems with their heating system which increases the risk of unexpected closure, according to a new report published by Bosch Commercial and Industrial.

Plate heat exchangers instantaneously generate hot water at the required temperature with flow rates measured in hundreds of litres per minute. Paul Sands, director of Stokvis Energy Systems, reports.

Portsmouth City Council has been able to make significant energy saving costs of nearly £30,000 per annum as well as permanently reduce the energy demands of the council’s Civic Centre building following the replacement of the aged boiler plant with three Ferroli Prextherm RHS Tonda 1400kW steel shell boilers. PWE reports.

Pumping applications account for more than 20% of global electric motor energy consumption and conscientious plant owners have been trying to maximise the efficiency of this equipment for many years. This task is made more difficult for older equipment for which the full specification data is no longer available or has been re-appropriated for a new task. Jerry Ruc, field engineer with Sulzer, looks at some common causes of poor performance and suggests methods of improving efficiency.

PWE spoke to Andy Jones, managing director at Mattei to answer questions on compressor energy efficiency.

Following a late rush of UK companies seeking to comply with the requirements of the Energy Saving Opportunities Scheme (ESOS) earlier this year, it is estimated that around two-thirds of approximately 10,000 eligible organisations are now registered. However, meeting the registration deadline should be seen only as the beginning, not as the end of the process. Dirk Ville (pictured), general manager, Atlas Copco Compressors UK and Ireland, reports.

CHP plants that meet the requirements of the CHPQA scheme qualify for a number of valuable benefits. Alan Hunt, product specialist for ABB Measurement & Analytics in the UK, explains how measuring CHP plant performance through good instrumentation is the key to gaining them.

PWE looks at a single-source HVAC and building-management control system for an oil sands project that is helping to improve maintenance, streamline the supply chain and keep production running.

Maintaining effective control of humidity is essential in industrial environments for both the health of the building and its occupants and, very often, supporting optimum performance of manufacturing processes. John Barker of Humidity Solutions explains.

Forthcoming European regulations will have an impact on the choice of space heating equipment in the future. Melanie Sadler, Engineering Manager with Powrmatic, provides an overview of the changes to come

While the air around us is free, compressed air used in industry is very expensive. Mark Stone, product manager at Flexion, part of ERIKS UK, explains how to deal with wastage and misuse.

Steam is a very versatile and efficient carrier of energy and it is used in a wide range of industrial processes. It is intrinsically safe and frequently used in food and pharmaceutical production; however, it must be treated with respect. The apparatus used to convey and control steam must be properly designed and maintained to avoid energy losses as well as damage to boilers and other plant by water hammer, which can be particularly destructive when left unchecked. Ian Webster, hygienic processing field segment manager at Bürkert UK and Ireland looks at this condition and how it should be avoided.

PWE takes a look at a new all-in-one kit that aims to rapidly increase the adoption of compressor energy recovery and simplifies integration with a building’s central heating and hot water system.

Implementing and maintaining an environmental strategy is all-too-often seen as less business-critical than other areas such as product development, innovation or machinery maintenance. Phil Burge, country communication manager at SKF, makes the case for supporting a sustainability agenda and explains how it can boost profits and performance.

Improving the efficiency of electrical conversion and new methods of thermal management may mean that in future motors run far cooler than they do today. But until then, heat dissipation remains a major consideration for designers of motor-driven systems. Bill Bertram, of motor maker Marathon Electric, looks at the state of the art and casts one eye into his crystal ball.

What is the energy manager's best-kept secret? Jeff Whittingham, managing director, DONG Energy for Business, tries to answer this question.

The clock has begun ticking towards December 2015. That is the date by which all UK companies with 250 or more employees, or annual turnover in excess of £42m, must have completed a comprehensive audit of their energy use. Keith Findlay, AIRScan manager, Atlas Copco Compressors looks at expanding on Energy Savings Opportunities Scheme (ESOS) regulations to secure compressed air energy savings.

PWE takes a look at a CHP solution, which was installed at one of the UK’s largest water parks.

UK Legionnaires’ disease is an underreported and severe form of pneumonia transmitted by pathogens in water. Anthony Barnett, technical marketing manager of Armacell reports.

Contemporary commercial gas boilers bear little resemblance to either their early ancestors or even the models which dominated plant rooms beneath offices, schools, shops, offices, hospitals and other premises in the second half of the last century. Indeed they have been transformed in terms of not merely their efficiency, but their scale, reliability and safety implications. Paul Sands, director of Stokvis Energy Systems reports.

From 16-17 September, the NEC Birmingham will host the UK’s leading energy efficiency, management and procurement exhibition and conference, The Energy Event. PWE reports.

Amin Almasi examines integrally-geared compressors for HVAC and plant applications for PWE

With the UK facing pending shortages in energy reserves on the national grid, Leslah Garland spoke with Billy Durie, critical services development manager at Aggreko Northern Europe, about the company’s key services and focus.

Over a five-year year period, a properly focussed maintenance plan will save at least half the cost of unplanned production stoppages caused by thermal fluid breakdown. However, the frequency of gathering sampling data for a heat transfer fluid, on which the maintenance plan depends, is determined by whether the fluid is mineral or synthetic. Clive Jones, managing director of Global Heat Transfer explains.
