Boiler description
The automatic hot water boiler TKA BIO 80 allows you to automatically burn wood pellets with a diameter of 6 - 10 mm, quality white, but also with a mixture of bark. A retort burner is installed in the boiler, which is designed on the principle of lower fuel supply to the combustion section and the combustion itself resembles burning in a forge. From the feed chamber, the fuel is fed by a feeder into the cast-iron retort tube. Here it is pushed upwards onto a circular grate. The retort is placed in a stirrer into which air is blown by a fan. The burnt fuel - ash and slag - falls over the edges of the grate into the ash tray.
The ROJEK TKA BIO 80 boiler is supplied with a 800 l fuel storage on the right or left side.
The boiler is equipped with a modulation unit ST 480 zPID.
This unit controls:
-
This unit controls:
- the burner fan (continuously controls the fan speed)
- the fuel feeder (controls the dosage according to the required output)
- the central heating circulating water pump (DHW)
- the hot water pump
- the boiler circuit pump
- the circulation pump
The controller includes a module for controlling a four-way or three-way mixing vent in the base. Furthermore, the ST 480 zPID controller can work with an equithermal sensor, with other four-way or three-way vents, with a room thermostat, with a GSM module, with a Wifi module and with an Ethernet module (via the Internet).
These hot water boilers meet the requirements of EN 303 - 5, Boiler Class 4 for pellet boilers.
