RHK-AK biomass boiler

Output range:
30 - 990 kW

Efficiency:
> 90 %

Fuel:
Woodchips as per EN 17225-4
A1/P45 M30, pellets

Combustion chamber:
8 mm wall thickness, refractory lining
in heart shape made from resistant
refractory concrete
Heat exchanger tubes:
6.3 mm wall thickness, large volume
register pipes with 200mm diameter,
seamlessly welded with cleaning
augers and brushes inside. Maintenance-friendly cover
Horizontal heat exchanger:
A natural air draught is created
by the horizontal heat exchanger,
resulting in a reduced electricity
demand and an improved heat
yield. Thanks to the robust cleaning
augers, rolled from 8 mm thick steel,
the heat exchanger cleaning is prac-
tically maintenance free! A high level
of efficiency is created at the lowest
of fluegas temperatures.
Automatic ash removal:
The ash from the combustion cham-
ber is moved through the patented
de-ashing chain, the heat exchanger
is cleaned via augers.
Combustion chamber with best emission values
Ash container:
Optionally 40 l, 240 l, 400 l or 900 l
Insulation:
80 mm sandwich panels
Air jet ignition:
A robust glow bar is used for ignition
mode. Placed in the air jets protected
from ash and soot. Energy saving,
just approx. 0.15 kWh per ignition!
