Howden rotary regenerative heat exchangers are used in boiler as air preheater, in flue gas desulfurization plant as gas/gas heaters and in tail-end selective catalytic reduction DeNox plant as gas preheaters. Our experience dates back to 1923 when we worked with Fredrik Ljungstrom to develop this type of equipment for use in utility boilers.
Howden also supplies replacement element baskets for rotary regenerative heat exchanger, (rotating or stationary matrix types), irrespective of original manufacturer. Over the past decade Howden has won more than 2000 contracts to supply replacement elements for air preheaters and FGD gas reheaters manufactured by more than 40 original equipment manufacturers.
With a range of over 45 different profiles, Howden can supply direct replacements of all element type commonly used in rotary heat exchanger, or offer alternatives which will improve the performance of the air preheater.
