Agricultural Anaerobic Digesters: Design and Operation

Dec 01, 2016 · The gas-fired cast-iron boiler was of commercial manufacture, of a type that would normally be fueled with LP gas. (0.45 kg) LP gas per day. A 40-gal (150-liter) water heater was operated experimentally, using biogas as fuel. and at 32°F (O°C) it will contain only 0.3 lb H 2 0 per 1,000 cubic feet (5 g/m 3). As the gas cools upon

Boiler - Wikipedia

When water is converted to steam it expands to over 1,000 times its original volume and travels down steam pipes at over 100 kilometres per hour (62 mph). Because of this, steam is an efficient method of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feedwater treatment, a

The role of hydrogen and fuel cells in the global energy

Prices are converging at around $10 000 per kW; a price point which solar PV modules reached in 1990. 148 Other issues such as product lifetime and reliability have improved significantly, to the extent that a fuel cell CHP unit is now equivalent in both these respects to a modern gas-fired boiler. 149–154

Sulfur Burning - an overview | ScienceDirect Topics

Figure 3.4. Entrance to fire-tube boiler from Fig. 3.3 's sulfur burning furnace. 1150 °C gas leaves the furnace, turns 90° into the boiler and flows into the hot gas boiler tubes. The tubes are surrounded by water. Heat is transferred from the hot gas to the water—cooling the gas and making (useful) steam typically at 40 or 60 bar.The tubes are typically 0.05 m diameter.

Combined cycle gas turbine – On its own, the best efficiency is GE's H series, which claims 60% efficiency. Direct gas turbine – high 30's% efficiency, or straight steam boiler with about 40% efficiency (now obsolete). All of these have potential for CCS. Methane when burned gives CO2 and water, the latter is easily separated. With high
