The KSM boiler is certified by an accredited laboratory to meet the energy and emission requirements of class 5 in accordance with the 303-5:2012 standard, which makes it possible to obtain co-financing for the purchase of equipment up to 50%. This furnace has a high heating power with a relatively small size, so we can install it in smaller boiler rooms. In the KSM boiler, eco-pea obtained from hard coal is used as the basic fuel. The exchanger construction has a vertical system of flue gas ducts, which results in a high efficiency of up to 90%. KSM has two independent systems to protect the boiler operation:
KSM has two independent systems to protect the boiler operation:
- Electronic sensors are responsible for maintaining proper worm and water temperature in the boiler. If the temperature is exceeded, the feeder and fan operation is stopped and an alarm signal is activated. If the feeder pipe reaches too high a temperature, the flame extinguishing system will be activated. Electronic sensors also protect against freezing of water in the system. If the ambient temperature is less than 5°C, the reaction of the sensors starts the process of activating all the pumps, which enable water circulation in the system.
- The STB mechanical sensor is an additional protection. When the safe temperature of water for the boiler is exceeded, the STB sensor will switch off the blowing and stop the fuel feeder and start a sound signal.
