Dec 01, 2016 · The manufacturer's rating for boilers indicated a boiler efficiency of 0. 7 with LP gas and 0.78 with natural gas. The value of 0.58 was used in calculating the needed boiler capacity due to intermittent and low-load operation. A boiler with a rated input value of 66,000 Btu/hr (19.5 kW) was selected for the Penn State digester installation.
Read MoreOne is stand by while 2 are in operation. Water Tube Boiler A Water tube design is the exact opposite of a fire tube. Here the water flows through the tubes and are incased in a furnace in which the burner fires into. These tubes are connected to a steam drum and a mud drum. The water is heated and steam is produced in the upper drum.
Read MoreThe vertical gas velocity is 3.5 m/s in the afterburner chamber at a thermal load of 25 Gcal/h. The off-gas at a rate of 66,000 Nm3/h leaves the afterburner chamber at a temperature of 1000°C. Heat is recovered in a steam boiler. The gases leave the boiler at 270°C. Steam is generated at 25 atm and superheated to 250°C at a rate of 34 t/h.
Read MoreHeat is transferred to steam pipes located in the top region of the boiler, these being initially fed with hot water from the boiler feed pump; the hot water then gets converted to steam at high temperature and pressure. This steam is fed to the steam turbines which are the prime movers for electric generators. 89
