Terminology

Aphodid Boiler or Burner (APB): A container within which gaseous fuels are burnt inside _L.H₂O or _G.H₂O. An APB normally has well insulated walls made of high tensile strength materials so it can contain high Ts and Ps.

Biowaste: Organic materials such as kitchen garden, and slaughterhouse wastes that can be fermented anaerobically to fertilizer and biogas. Biowastes can contain poisons that kill methanogenic bacteria. Waste paper usually biowaste - but print on it may be toxic. Tannery and paper factory wastes can be poisonous

Biogas: is a mixture of CO₂ and bioCH₄,

BioCH_4, BioH₂, BioCO₂: Gasses obtained from non-fossil sources

Enthalpy: H. Internal energy of a mass kJ/kg. According to definition H = P x V + U Where: P = pressure, V = volume, U = LQ + SQ.

Entropy: S. that part of the Q in a mass of working fluid that cannot be converted into W according to the Second Law of Thermodynamics. S gained between two Ts is computed as the sum of the kJ/(kg x K) for all K degrees  

Fluid: A substance which is used in both its liquid and its gaseous phases.

Pyrotrash: Old plastics and rubber, used tires, lubricating oils, plastic solvents and paint thinners. Biowastes containing poisons, parasites and pathogens can be treated as pyrotrash.
