Technical data

Description:
The PYROT Rotation Heating System (patent no: EP 0 905 442 B1) was developed for automatic incineration of all dry
to moist wood fuels (remnant wood, pellets and forest woodchips to max. W35-40).
The PYROT Rotation Heating System is characterized by high efficiencies and perfect incineration at all load levels. The
PYROT Boiler Plant has been tested and approved in accordance with the latest quality criteria as per EN 303-5 Heating
Boilers for solid fuels, CE-certification in accordance with European Machinery Directive with continuous quality
inspection by the TÜV.
Max. forward flow temperature allowed: 250°F / 121°C
Max. operating pressure allowed: 30 or 60psig
Safety heat exchanger: Built into the boiler
How it functions:
- The feed auger conveys the material to be burned diagonally from below into the firing system. The holding devices
for the burn-back sensor and the thermal extinguishing valve are situated on the conveyor pipe. Above the auger,
there is a metering container with a light barrier to ascertain the level of the fuel isolating layer required according to TRD 414.
- The material to be burned is ignited automatically by an electric heat gun. The gasification of the fuel is carried out on
a feed grate moved by a worm-geared motor. The ash falls in an ash bin below. An automatic de-ashing system is
optional. The fire block is lined with highly refractory insulation and fired refractory concrete elements.
- The combustion gases rising from the fire block are swept up by the rotating secondary airflow brought to bear by the
rotation blower and burned out completely in the round combustion chamber. The thermal energy from the
combustion gases is transmitted to the boiler water in a horizontally positioned pipe-type heat exchanger. The boiler
is heavily insulated, cased in an aesthetically pleasing fashion and provided with excellent access through the boiler
door on the end side. On the rear side of the boiler there is a flange for an oil burner, which is closed by an insulated
blank lid with an inspection window.
- A flue gas re circulation system reduces the temperature in the fire box while maintaining the highest possible degree
of efficiency. This increases the service life of the un-cooled refractory elements in the incineration zone. With the
basic setting, the ratio of re-circulated gas to fresh air is geared precisely to the material to be burned. A mechanical
flow volume regulator provides a constant ratio of the quantity of re-circulated gas to fresh air over the entire output range.
- The flue gas fan is specially designed for wood heating operation and is very quiet. The motor has a solid, heat resistant
design with a heat dissipation hub and is spring-supported. The fan casing on the intake port turns in infinitely variable fashion.
The blow-out nozzle is round. Installation is possible on the top, side or rear of the flue gas collector. Included in the delivery:
- Feed auger with isolating layer, incl. extinguishing valve with dirt trap, extinguishing water container with holding device
