Encyclopedia > Producer gas

USA

Producer Gas is a generic term referring to:

  • Wood gas : produced in a gasifier to power cars with ordinary internal combustion engines.
  • Town gas : manufactured gas, originally produced from coal, for sale to consumers and municipalities.
  • Syngas : used as a fuel source or as an intermediate for the production of other chemicals.

Town gas is a generic term referring to manufactured gas produced for sale to consumers and municipalities. ... It has been suggested that Town gas be merged into this article or section. ...

In the UK, Producer Gas, also called Suction gas, specifically means a fuel gas made from coke or other carbonaceous material. Air is passed over the red-hot carbonaceous fuel and carbon monoxide is produced. The reaction is exothermic and proceeds as follows: Coke Coke is a solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. ... This article belongs in one or more categories. ... Carbon monoxide, with the chemical formula CO, is a colorless, odorless, and tasteless gas. ... In thermodynamics, the word exothermic describes a process or reaction that releases energy in the form of heat. ...


2C + O2 → 2CO


The nitrogen in the air remains unchanged, and dilutes the gas, so it has a very low calorific value. After "scrubbing", to remove tar, the gas may be used to power gas turbines which are well-suited to fuels of low calorific value. General Name, Symbol, Number nitrogen, N, 7 Chemical series nonmetals Group, Period, Block 15, 2, p Appearance colorless gas Standard atomic weight 14. ... Heating value (or calorific value) is used to define the amount of heat released during the combustion of a fuel or food. ... Tar can be produced from corn stalks by heating in a microwave. ... This machine has a single-stage centrifugal compressor and turbine, a recuperator, and foil bearings. ...


Producer gas is a useful gas but requires careful handling because of the risk of Carbon monoxide poisoning. Carbon monoxide poisoning occurs after the inhalation of carbon monoxide gas. ...

Gas - Wikipedia, the free encyclopedia (681 words)
A gas is one of the four main phases of matter (after solid and liquid, and followed by plasma), that subsequently appear as a solid material is subjected to increasingly higher temperatures.
The thermodynamic state of a gas is characterized by its volume, its temperature, which is determined by the average velocity or kinetic energy of the molecules, and its pressure, which is determined by the average velocity and density or number of molecules.
The word "gas" was invented by Jan Baptist van Helmont as a phonetic spelling of the Flemish pronunciation of the Greek word "chaos".
Gas Engines and Producer Gas Plants (10186 words)
Producer gas had previously been used for heating purposes, in which case it was desirable to keep the temperature of the gas as high as possible before being burned.
When the gas from the blast furnace is not sufficiently cleaned before it goes into the gas engine, the dust collects on the inner surface of the cylinder, and, as the piston moves to and fro, the dust is ground between the piston and cylinder, thus causing excessive heating and perhaps cutting of the surfaces.
The temperature of the gas is also reduced by the water, the amount varying from 60 to 260 degrees F., depending on the temperature of the blast-furnace gas, the temperature of the water, and the efficiency of the cleaner.
