Step-by-step regulation of boiler power

Stepped power control boiler is a method of controlling the thermal power of heating equipment, in which boiler or other heating unit can operate at several preset power levels. Unlike smooth or modulating regulation, step regulation involves switching between fixed heating levels.

Step-by-step regulation of boiler power: features

1. Fixed power levels:
   • The equipment can operate, for example, at 30%, 60%, or 100% of its power, depending on the needs of the system. This helps to regulate the heat level more precisely than in the on/off mode, but is less flexible than modulating control.
2. Fuel economy:
   • Step control allows you to save fuel, since the system does not operate constantly at maximum power, but uses only the required amount of energy to maintain the set temperature.
3. Simplifying management:
   • Implementation of step regulation requires a less complex control system compared to smooth modulation. This makes this method more affordable in terms of equipment cost and its adjustment.
4. Use in boilers and burners:
   • Most often, step-by-step power regulation is used in heating boilers, burners and ventilation units. It allows for efficient adaptation of equipment operation to changing heat loads, such as changes in outside air temperature or temporary reduction in heat consumption.
5. Example of application:
   • In pellet and solid fuel boilers, step regulation allows for more precise adaptation of the supply of fuel and combustion air depending on the heat requirement.

Step-by-step regulation of boiler power is often used in industrial and domestic heating systems where reliability and ease of operation are required.
