Boiler Stalmark EKO Pionier 20 kW
EKO Pioneer by Stalmark is an eco-coal boiler that meets energy-emission class 5 requirements according to the PN-EN 303-5:2012 standard. Thanks to the implementation of modern solutions, the boiler is characterized by high efficiency and environmentally friendly combustion. The boiler, in automatic mode, burns eco-coal with a granulation of 5-32mm.
Boiler Construction
The boiler heat exchanger is made of certified boiler steel with a thickness of 6mm. One of the designers' objectives was to eliminate as many welding connections as possible by bending the steel. Additional plates were placed in the combustion chamber to increase the temperature and combustion efficiency. To minimize heat losses, insulation with mineral wool was placed between the heat exchanger and the housing.
Boiler Controller
The Stalmark EKO Pioneer is equipped with the modern TECH ST-750 controller with PID, which offers great expandability. The PID algorithm is designed to optimize the boiler's operation, resulting in fuel savings. It is assumed that the use of this algorithm can achieve savings of up to 25% with correct settings and fuel parameters. The controller allows the operation of up to four pumps and one valve simultaneously. Additionally, its capabilities can be expanded by connecting the GMS and Ethernet modules.
