Stove Notes:

article: "Improved...Stoves" by Bill Stewart

-Make the combustion process as efficient as possible

-Heat transfer to room should also be as efficient as possible

Analysis of Bagasse: Carbon (48); Hydrogen (6); Oxygen (46)

Analysis of Peat: Carbon (60); Hydrogen (6); Oxygen (32)


Combustion heat value of Bagasse: 19.26 MJ.kg
Combustion heat value of Peat: 23.3 MJ.kg


Three main modes of heat transfer= Conduction; Radiation; Convection

Notes from class 5/10

Humidity:

Ideal for day- 25%-70%

Over night- usually gets to 100%

FANS: should run continuously during high humidity (i.e. overnight & during rainy days- or else plant disease could result

Ventilate it each day as dusk in the winter

Insulation:

Here are some of the most used types of greenhouse insulations: double-glazing, flexible plastic, thermal screens and base cladding.

safety & maintainance:

-automated oven- when temp gets so low biochar is mechanically added (someone does not need to constantly maintain oven)

ideal- get up to temp then change it to maintain a steady temp.

is pyrolysis right
