  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Enhancing the dynamic performance of electricity production in steam power plants by the integration of transient waste heat sources into the feed-water pre-heating system

    Since the deregulation of the energy market the enhancement of steam power plant's dynamic performance has become more and more important. Nowadays, peak load is a profitable product at the energy stock markets if it can be provided reliably. This is in contrast to many power plants running constantly at full load. A very promising technique to improve the peak load capability of such power ...

  • 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 ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • The effect of precooling inlet air on CHP efficiency in natural gas pressure reduction stations

    Almost all pressure reduction stations in Iran use expansion valves to reduce the natural gas pressure, which leads to wasting large amount of exergy. In this paper, a system is proposed which includes the modification of a conventional pressure reduction station with the addition of a turbo expander and a gas turbine for power recovery and generation. The next step is investigating the effect of ...

  • Clean energy: How much hot air?

    NewScientist’s January 28 issue is likely to unsettle clean energy advocates – but it is worth the read. The cover article, “Power paradox: Clean might not be green forever,” posits that even renewable energy can warm the planet, and eventually change ...

  • Pushing the Limits of Reengineering

    Cutting-edge turbine technology enables more efficient and cleaner power generation. However, the service of advanced gas turbines is challenging—especially when parts need to be replaced.
