  • Combustion Evaluation: Sources and Control Devices

    3. A steam heater may be used to pre- heat the air before it contacts the air heater proper. The last method is often acceptable where LP steam is available from a turbine. The loss of efficiency af the boiler is very nearly compensated by the increase in efficiency of the turbine. C.Get Price

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.Get Price

  • Common Steam Boiler Problems & How to Troubleshoot Repairs

    As with other boiler problems, clean the boiler of any contamination caused by foaming before correcting the water chemistry problem. Treating the water with anti-foaming agents prevents the chain reaction caused by foam production. The chemicals alter the surface tension to prevent any solids from creating foam in the water.Get Price

  • Spotting, Staining, and Corrosion of Surgical Instruments

    Oct 01, 2000 · Spotting as a result of steam impurities can be avoided by making sure that the steam quality is kept high. This can be done by making sure that the steam and boiler water are monitored on a regular basis. Inadequate maintenance of the boiler can cause boiler chemicals to be carried over into the steam system.Get Price

  • Sugarcane bagasse ash as supplementary cementitious

    Oct 28, 2021 · Nevertheless, the bagasse is commonly used as a propellant in the cogeneration boiler at present to produce steam and energy, which is employed in the refinement of the sugarcane juice into raw sugar at a sugar mill. Generally, the bagasse is burnt about 500–550 ºC in the cogeneration boiler to expend its utmost calorific value.Get Price

  • Groundwater | Dissolved mineral sources and significance

    Carried over in steam of high-pressure boilers, silicas form damaging deposits on the delicately balanced blades of steam turbines. Silica also inhibits the deterioration of zeolite-type water softeners, but does not affect water for domestic purposes. Groundwater generally contains more silica than surface water. IronGet Price

  • OSHA Technical Manual (OTM) - Section IV: Chapter 2

    Steam Distribution. The distribution system consists of valves, fittings, piping, and connections suitable for the pressure of the steam transported. Steam leaves the boilers at the highest pressure required by the process units or electrical generation. The steam pressure is then reduced in turbines that drive process pumps and compressors.Get Price

  • Boiler water treatment - Lenntech

    The treatment and conditioning of boiler feed water must satisfy three main objectives:.
