Raising the game
Many commercial and industrial processes present widely variable or even intermittent demands for steam. Operations engineers looking to reduce costs and improve efficiency, whilst keeping emissions to a minimum, are turning to the next-generation of rapid steam-raising plant
Blowing hot and cold
Last summer's government energy strategy - which called for power generation from renewables to rise to 20% by 2020 and for CO2 to be reduced by 60% before 2050 - is going to have a profound effect on plant, and that includes HVAC (heating, ventilating and air conditioning) installations. That's particularly the case in non-domestic buildings, where space and water heating account for significant energy use and emissions. And it's not only about increasing the use of air source and ground source heat pumps, or solar hot water systems: variable speed drives (VSDs) on existing fan and pump equipment, as well as CO2-based building energy controls are among other technologies that need to play their part.
