Results of bench‐scale tests on the rheological and calorific properties of peat/water/No. 4 fuel‐oil mixtures indicated that a peat/water/oil (PWOM) slurry with rheological characteristics and calorific properties suitable for combustion in conventional boilers can be prepared using 40% (by weight) peat, of – 246.4 μm particle size and 40–45% natural moisture content, in the presence of 1% Cab‐O‐Sil PTG as a stabilizing additive. This low cost liquid fuel has a calorific value about 80% of, and a flow rate about 1.2 times the corresponding values for fuel oil No. 4. An economic feasibility study was conducted based on a PWOM cost to the consumer 10% below the cost of No. 4 fuel oil, and no ‘rent’ cost to the PWOM producer for the peat resource. The study shows that a project to harvest 112,000 tonnes of peat per year and to produce 282,000 tonnes of PWOM fuel is profitable for a range of assumed cost factors.
