Pyrot Technical Data
Wood Fuel Requirements
(continued)
Maximum water content
The maximum allowable water content of the fuel for
Pyrot systems is limited to 35%.
The water content impacts the maximum boiler output.
Non-wood fuels
Non-wood fuels, even if consisting of biomass, such as
needles, foliage, grain, straw, fruit pits, etc., are unsuited
as fuel for boiler operation and may not be used.
Limitation super fines & dust [wood particles smaller than
1
/
32
in. (1.0 mm)]
Max. 10.0% of the total mass; if fuel does not comply
with this limit the following process may occur:
- Temperature peaks
- Slag formation
- Even higher temperature
- This process leads to damage by overheating and
can affect refractory materials.
Elevated values are especially critical for remnant wood in
combination with elevated values of Chlorine and Sulphur.
General Information
Suitable fuel types for Pyrot systems
- Bulk density ( S ) in kg/m³ [lb/ft³], water content ( W ) in %,
size C1, C7, P1, P2, P4 as per CAN/CSA-B366.1-M91.
Note: Fuel for Pyrot systems allow for a max. of 35%
water content ( W ).
