|Wight Heat wood briquettes have a heating value of 4 kW per kg at 80% burn efficiency and can be used on woodburners, multifuel stove, AGAs and Rayburns, open fires, B-B-Qs and chiminera. Almost any biomass can be briquetted. Briquetting plants in India are using the following:
- Bamboo dust
- Cotton stalk
- Coffee husk
- Groundnut shell
- Mustard husk/stalk
- Pine needles
- Rice husk
- Sugar mill waste
- Jute waste
- Coir pith
Other wastes and residues like castor shell, red gram stalk, tobacco stem, tea waste, sander dust, tree bark, wild grasses and shrubs and sander dust can be also be briquetted WITHOUT USING ANY BINDER. They will burn differently depending on their composition and the efficiency and ash residue will vary. Briquettes are a good substitute for, or can be used with, coal, lignite, woo. They offer numerous advantages:
- There is no sulphur in Wight Heat briquettes.
- Wight Heat briquettes have a higher practical thermal value and much lower ash content (2-10% as compared to 20-40% for coal).
- There is hardly any ash (0.04%) when burning briquettes, depending on the combustion system.
- Wight Heat briquettes have a consistent quality, have high burning efficiency, and are ideally sized for complete combustion. Combustion is more uniform compared to coal and boiler response to changes in steam requirements is faster due to higher quantity of volatile matter in briquettes.
- Unlike coal, lignite or oil, Wight Heat briquettes are produced from local source that would otherwise go to landfill,
- Wight Heat Briquettes have high specific density (up to 1200 kg/m3) compared to 60 to 180kg/m3 of loose biomass.
- Wight Heat Briquettes are clean to handle and can be packed in bags for ease of handling and storage.
- Wight Heat Briquettes are especially good for small stoves or wood burners as their size reduces the need to chop logs to the required size.
Do you know of a clean and dry supply of wood waste? Let me know and it doesn’t have to go to landfill.
