Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

Study of the performance and exhaust emissions of a spark-ignited engine operating on syngas fuel
To resolve the problem of depletion of petroleum based liquid fuels, various solutions have been proposed. One of them is the use of gaseous fuels that are generated from the gasification of woods, namely syngas or wood-gas fuels, as full supplement fuels in spark ignition internal combustion (IC) engines. This fuel consists of nearly 40% combustible gases, mainly hydrogen and carbon monoxide ...

Combined Heat and Power (CHP) essentials
'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

Cleaning biogas with bacteria
Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid (H2SO4). It is for this reason ...

Tronox Namakwa sands furnace Gas CHP Plant - Case Study
Tronox is the largest fully integrated producer of titanium ore and titanium dioxide in the world. The Tronox Mineral Sands cogeneration power generation plant, located in the Western Cape, uses the waste gas from two open arc DC furnaces as an energy source. The gas engine power plant operates on waste gas produced by titanium melting. The facility consists of 8 of GE’s JMS620GS-SL ...

Los Angeles County Sanitation Districts: Siloxane Removal
Los Angeles County Sanitation Districts have long been involved with recovering landfill and digester gas for energy to power turbines and internal combustion engines. Their experience led them to identify performance issues associated with these gases. One particular challenge is siloxanes. Cyclic organic silicon monomers (siloxanes) used in the manufacture of personal hygiene, health care and ...

Landfills types of technologies for converting LFG into Energy
A number of factors, including the availability of an energy market, project costs, potential revenue sources, and other technical considerations, can determine which technologies are most appropriate for a particular landfill gas-to-energy (LFGE) project. Technologies for converting LFG into energy include the following. Electricity Generation Approximately 70 percent of the LFGE projects ...

Fuel Cells Can Decarbonize California’s Buildings (While Keeping the Lights On)
California just faced historic blackouts. In fact, it endured three of the largest planned power outages in state history. The era of intentionally cutting off power to residents and businesses across the state to prevent wildfires – known as Public Safety Power Shutoffs (PSPS) – has arrived, and it’s highlighting the urgent need for energy solutions that address both the causes ...

Building New Industries and Creating New Jobs in a Plan B Economy
Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

Improve Boiler Efficiency
In many chemical plants, the electricity the plant uses is derived from a natural gas power plant or a co-generation plant burning waste gas streams. In large boilers (Figure 1), power plants bring together air and fuel (natural gas, waste gas, oil or coal) for combustion, which creates heat. The heat boils the water, creating steam. The steam runs through a turbine, which causes the turbine to ...

Hydrogen as Future Fuel for Gas Engines
Gas engines are providing a wide range of fuel flexibility from burning natural gas and a variety of non- natural gaseous fuels from low British Thermal Unit (BTU) gases as well as gases containing a high hydrogen content. Hydrogen containing gases can be found as by-product from steel (furnace gas) or chemical process, or alternatively hydrogen is produced and blended to natural gas. In the ...
