  • Economizer - Wikipedia

    The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economiser.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.Learn More

    the idea of reducing the cost of steam, and the result has been reflected by at least doubling the efficiency of the bagasse fired boiler. With the old-fashioned plant it was considered quite satisfactory if a boiler gave an efficiency of 40%, and very often mills would run for long periods …Learn More

  • Exhaust Gas Boilers And Economisers for Marine Machinery

    Our broad line of economizers covers the spectrum of boiler sizes, ranging from very small hot water boilers with burner inputs of 200,000 BTU/hr to large boilers delivering steam at 250,000 lb/hr. In addition, Cain produces boiler feedwater systems, condensate tank and pump systems, exclusive sootblower assemblies, and unique modulating Learn More

  • BOILERS | Energy-Models.com

    Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.Learn More

  • Reheaters - an overview | ScienceDirect Topics

    Double-RH thermal power plants have nearly 450 m of pipework between the boiler and turbine, manufactured from high-cost materials, against 150 m of such pipework for a single-RH plant.Therefore, alternative boiler-turbine configurations could reduce the length of the pipework and thus dramatically reduce capital costs.Learn More

  • Primary circuit or boiler shunt pumps in commercial heating

    A single primary circuit pump application is where the entire primary circuit flow is dependent on a single large pump. This pump needs to be capable of circulating the entire primary circuit at the minimum flow rates specified for the boiler or boilers whilst overcoming the resistance created by the heat exchangers, pipework, fittings, and any resistance created by hydraulic breaks such as Learn More

  • Boiler retubing & boiler tube replacement

    IB&M's boiler retubing process includes: Inspection - IB&M visually inspects each boiler, and perform NDT testing as needed. We use dye penetrant testing to expose areas of boiler tube sheet cracking. Boiler Tube Extraction - old boiler tubes are removed along with the tube ends. Any minor tube sheet cracks are then repaired to the ASME code specifications.Learn More

  • Water Treatment – D.J. Conley

    Jun 19, 2020 · A word about Boiler ECONOMIZERS on steam boilers: If you have multiple boilers, each having a flue gas economizer, and one or more boiler is in hot stand-by, it is recommended that a by-pass line with orifice be installed. This will recirculate water from a common feedwater header at economizer, to outlet piping of economizers, back into the Learn More
