2.1.2 Boiler Fabrication and Testing
The boiler is shipped on one pallet that includes the assembled boiler. Depending on accessories pur-
chased with the boiler, additional packages for accessories may be loaded into the firebox or attached
to the pallet. The boiler is shipped with the refractory bricks installed.
Solo Plus boilers have been tested and listed for safety and performance for the U S and Canadian
markets by OMNI Test Laboratories, Inc.. The test standards used are UL 391 and CAN/CSA B366,
and 1-M91. The boilers are UL listed. The boiler is not ASME stamped. The installer should follow
local or state installation requirements.
The Solo Plus wood gasification boiler is a log wood fired boiler designed and constructed for highly
efficient combustion of log wood. Do not burn other fuels in the Tarm Biomass Solo Plus boiler. The
Solo Plus
is not
a self contained weather-tight boiler. It should be installed within the heated building.
2.1.3 Models and Applications
Three Solo Plus models are available (the model 30, 40, and 60), with rated heat outputs of
102,000Btu/hr (30 kW), 140,000Btu/hr (40 kW), and 198,000Btuh/hr (60 kW), respectively. Specifi-
cation data for each Solo Plus boiler is provided in Section 6.3.
The boilers can be utilized as a single heat source, or in parallel with another boiler. They are appro-
priate for both residential and nonresidential applications, as well as applications using heat storage.
2.2 Boiler Function
2.2.1 General Operation
Provided below is a simplified discussion of operation of the boiler to provide a brief familiarization
with operation. Please refer to the cut-away view of the boiler in Section 2.1.1.
With the by-pass damper open
(1),
a small fire is kindled in the firebox
(13).
After the fire has been
established, the firebox is opened
(3)
and loaded with the batch of wood to be burned during this fir-
ing. After loading, the load door
(3)
is then closed. The by-pass damper
(1)
is pushed shut and the
draft fan
(9)
is turned on to force combustion gasses down through the base of the firebox where sec-
ondary air is injected. After leaving the firebox, the gases and secondary combustion air enter the re-
fractory tunnel
(14)
where in a turbulent environment the gasification combustion takes place. This
gasification combustion produces gases with temperatures exceeding1800 ºF (980 ºC). This high tem-
perature combustion is extremely efficient and virtually smoke and creosote free. The hot gases then
pass along the bottom of the boiler toward the back, where they rise upward through the heat ex-
changer tubes
(12)
transferring heat to water in the boiler and exit through the flue outlet
(10)
.
The boiler serial number plate
(8)
indicates factory no. and type and other information required to
order spare parts. Factory no, and type can be noted in
Section 8
.
Detailed instructions for operating the Solo Plus boilers are given in Section 4 of this manual.
