Sentence examples for coal at low from inspiring English sources

But of 1,617GW of global capacity, 75% is of the dirtiest kind, which burns coal at low temperatures and emits 75% more carbon dioxide than the most advanced (and costly) "ultra-supercritical" plants, which burn powdered coal at high temperatures.

The high ash in the fractions reflects that recovery of clean coal at low specific gravity is difficult to achieve.

But, without the policy, or market, change, the economic barrier is a strong one, when biomass cofiring must compete with low-cost coal at low fuel cost and with low-capital-cost gas turbine combined cycle power plants.

The mechanism of the oxidation of coal at low temperatures, i.e., below 100°C, was examined using measurements of the gases emitted from a bed of coal in an isothermal flow reactor.

A kinetic model has been developed for determining the rate of oxygen consumption and production of carbon oxides during the oxidation of coal at low temperatures (i.e. <100°C), based on current understanding of the mechanism of coal oxidation.

The same models were used to assess the relevance of gasification in oxy-combustion conditions; gasification may account for as much as 20% of the overall char consumption rate in the combustion of a low rank coal at low O2, high CO2 concentrations and offset (and exceed) the loss in the oxidation rate due to the change in diffusivity.

Prior to use as modified brown coal, three modification methods including drying to dewater by using low-temperature fluidized bed, coal pyrolysis at low temperature, and coal briquetting have been done, respectively.

In this paper, an integrated instrumentation system is developed to continuously monitor the pulverized coal flow within a 30 mm horizontal pneumatic pipe on a pilot coal gasifier at low pressure.

Power plants using Victorian brown coal operate at low efficiency.

Because CT contains a small number of small molecules, the small molecules can quickly enter into the coal pores at low temperature.

Ether bonds were also easy to be dissociated during coal pyrolysis at low temperature, producing CO gas or carbonyl group, which should be the reason for the quantity of Al O decreasing (Reaction 2).
