Main failures of household gas boilers

  • Pure Steam Generation - AQUA-CHEM

    The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a large amount of steam on unit gas mass basis.Learn More

  • What is a Steam Boiler ? Types, Parts and Maintenance

    May 19, 2020 · Steam generators convert water into steam but in a single pass through the water coil transferring the hot gas into the desired output. Steam generators, on the other hand, are smaller than steam boilers since they don't use any pressure vessel.Learn More

  • Heat Recovery Steam Generator - HRSG, Waste Heat Boiler

    Oct 06, 2021 · Heat Recovery Steam Generator Structure. The waste heat boiler body adopts modular structure to facilitate transportation and installation. The module is composed of tube clusters, which is a serpentine tube assembly. Upper and lower header are at both ends of module, and water in the module is heated by high-temperature gas. In order to better transfer heat, fins are welded on outer surface of pipe to increase heat transfer area. Most of the modules are evaporator…Learn More

  • Options for Improving the Efficiency of Heat Recovery

    The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a Learn More

  • Configuration of Evaporators for Once-Through Heat

    May 21, 2019 · Abstract Various designs are examined of evaporators for horizontal or vertical once-through heat recovery steam generators (HRSG) of combined-cycle units. Special attention is given to the Benson boilers manufactured by Siemens, which are most widely used now. Vertical HRSG with evaporators having horizontal heating surface sections are also analyzed. Their advantages and …Learn More

  • Boiler Efficiency | How to balance steam loads efficiently

    Aug 26, 2011 · The reason is the bigger heat sink at the economizer at higher loads in the form of increased water flow. Unlike in a steam generator (Table 1), the exhaust gas flow is nearly constant in an HRSG, and we're only varying the firing temperature to generate more steam. Hence, the fuel utilization is better when generating more steam.Learn More
