2019-9-2 · Ron AJ's comment is typical, the refractory design of the firebox brings combustion temps up around 2000 F which is how the low emissions are achieved, then the heat is captured and cooled in the long flues usually entering the chimney at about 300 F The HeatKit Contraflow heater we typically build has tested emissions as follows PM .68 g/kg CO

Natural gas is primarily methane (CH4), which has a higher energy content relative to other fuels, and thus, it has a relatively lower CO2-to-energy content. Water and various elements, such as sulfur and noncombustible elements in some fuels, reduce their heating

On hot water bottles: the energy spent boiling that water is likely comparable to the energy an electric blanket on low power would use. For me, a thick down comforter on the bed pre-charged with heat via old-fashioned hot water bottle an hour before (they have nice, newfangled silicone models these days) was all it took. it is far more

The latter use LP drum water to add another 30 to 40 deg F before condensate enters the LP economizers at about 175F to 190F. Note that water samples for analysis are withdrawn downstream of the condensate pump and cycle chemistry is adjusted with chemical injections just ahead of the air-ejector condensers.

2016-12-1 · Hot water from a gas-fired standard cast-iron boiler (Figures 50, 51) was forced through the pipes by a circulation pump. The boiler was fired with LP gas for start-up and switched to biogas when production permitted. Thereafter, the boiler was operated on biogas entirely, except for its pilot light, which used LP gas continuously.

The standard configuration can accomodate a crew of six, with the strap-on boosters there can be only four. Assumes consumables of Oxygen 1.0 kg/person-day, Dried Food 1 kg/person-day, Food Water 2 kg/person-day, Drinking Water 1 kg/person-day, Hygiene/wash water 6 kg/person-day.
