5%+ Fuel Savings with BIB Cochran Economisers The BIB Cochran range of
Economisers are designed to recover heat from Boiler exhaust gases, and
transfer this to the incoming Boiler feed water, thus increasing the overall
Boiler Thermal Efficiency.
Design Features Two standard ranges of
Economisers are available, increasing the Boiler Thermal Efficiency by a
nominal 3.5, and 5.0%. The resultant fuel saving will be in the order of
4.25, and 6.0% respectively.
Both ranges are designed to limit the gas side pressure drop to less than 0.5 ˛ WG, and 0.5 bar on the waterside. The Economisers are manufactured from extended surface tubing, within a carbon steel casing. Removable covers give access to the tubes, which can easily be removed if necessary. They have a design pressure of 24 barg, and design temperature of 300 °C. They are CE marked in accordance with the Pressure Equipment Directive (97/23/EC). For dual fuel firing, when prolonged firing on oil is likely, the Units may be supplied with an integral gas bypass. The alternative to this is to incorporate a water bypass in the feed pipe work, thus allowing the units to “run dry”. The Economiser Units are ideally arranged for a vertical gas flow, but if used with a horizontal gas flow, then additional vent and drain connections are fitted.
