  • Automatic carbon dioxide enrichment strategies in the greenhouse: A review

    Exhaust gases from fossil fuels Enriching greenhouses with CO2 generated from burning fossil fuels has been commonly used, particularly in cooler northern areas. In rudimentary modes of greenhouse cultivation, growers directly burn coal to heat and fertilise greenhouses during the winter. A more advanced cultivation mode employs natural gas and other hydrocarbons as heat and CO2 sources…

  • Integrated Design of Energy Efficient Cities

    Simplified Analysis of Energy Performance of Boilers There are several factors that influence the energy performance of boilers including fuel characteristics, firing method, steam pressure, and heating capacity. The main challenge to ensure optimal operating conditions for boilers is to provide the proper excess air for the fuel combustion. It is generally agreed that 10% excess air…

  • MEASUREMENTS IN ASSESSMENT OF WEATHERING CONDITIONS

    POLLUTANTS The Global Atmosphere Watch was established in 1989 by the World Meteorological Organization to coordinate atmospheric pollution measurement. The primary measurements are determined for:• greenhouse gasses (carbon dioxide, chlorofluorocarbons, methane, nitrous oxide)• ozone and precursor gases (total column, vertical profile, and near the surface)• the turbidity of atmosphere, UV intensity, aerosol particles, and water vapor•…

  • Analysis of Substances in the Gaseous Phase

    The period up to the beginning of the twentieth century is characterized by ever-increasing interest in absorption gas analysis, from the points of view both of instrumentation and the method itself, as well as considerations of its usefulness. At the end of the 19th century, Hempel, Winkler, Bunte, and Orsat carried out important work and, together with…

  • Analysis of Flue and Fuel Gases

    Carbon Dioxide, Oxygen and Carbon Monoxide The apparatus normally used for the routine analysis of flue gas is the Orsat appparatus. The gases usually estimated are carbon dioxide, oxygen and carbon monoxide. The apparatus is illustrated in Fig. 122.1. It consists essentially of a water-jacketed gas burette, connected by a common line of coarse capillary tube and tapped connections to three…

  • Analysis of Substances in the Gaseous Phase

    Apparatus for the Analysis of Gas Mixtures Apparatus for the complete analysis of gas mixtures consists of a burette and a system of absorption or combustion pipettes. The Hempel apparatus consists of these burettes and absorption pipettes combined with combustion pipettes, which will be described in the chapter on combustion methods (Sect. 8.6). This classical…

  • Construction

    The apparatus consists of an intake valve which feeds into a calibrated water or glycerin jacketed gas burette, this burette is then connected by tubing to two or more absorption pipettes containing chemical solutions that absorb the gases it is being used to measure. The intake and each of the absorption pipettes are valved with stopcocks to allow the movement…

  • Orsat gas analyser

    An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use.[1] The apparatus was invented by Louis Orsat who reported it in the Annales des Mines…
