Modeling Nitrogen Evolution during Coal Pyrolysis Based on ...

Aug 25 2000 · The modified nitrogen model is the first to describe the rank dependence of nitrogen release as light gas without the use of correlations. The model is also the first to offer reasonable explanations for the observed release of ring nitrogen at relatively low temperatures and the inherent stability of much of the char nitrogen during pyrolysis.

Net zero and domestic hydrogen: a forthcoming marriage ...

May 06 2021 · When burnt in air which is 78 per cent nitrogen - as in an existing flame-combustion domestic boiler - the higher hydrogen flame speed means that the oxygen combines with nitrogen in the air to form up to six times the NO x emissions compared to burning natural gas in air. This presents a seriously increased health risk over natural gas.

Why I replaced my new gas boiler with a heat pump - Foresight

Jun 26 2019 · It means that after less than 1.5 years a heat pump starts saving carbon compared to a gas boiler even if the gas boiler is replaced before the end of its life. Hence from a carbon perspective it makes sense to replace a gas boiler even if it was just installed. Assuming a 20-year lifetime for the heat pump the embodied carbon emissions a ...
