Bunker filling controller — is a device designed to automatically control the filling level of a bin with various materials, such as fuel (e.g. pellets), grain, sand and other bulk substances. It monitors the content level using sensors and, if necessary, activates or stops the material feed, preventing both overfilling and complete emptying of the bin. The controller ensures uninterrupted operation of systems, minimizes manual intervention and increases the efficiency of the material feed process.

Hopper Filling Controller: Capabilities

Most of our customers pay special attention to the level of heating comfort and the possibility of work automation. solid fuel boilers, characterized by increased labor intensity of maintenance. An important factor is the possibility of automating the filling of the supply hopper, reducing the share of manual labor. The hopper filling controller is designed precisely for these purposes.

The automation controls the storage bunker auger:

• controls the minimum level of the boiler feed hopper
• controls the filling and maintenance of the operating level of fuel in the supply hopper from the storage hopper
• automatic and semi-automatic filling of the feed hopper
• Upon additional request, it is possible to install a lower feed hopper sensor
• work on capacitive level sensors with adjustable threshold (low sensitivity to dust), guaranteed control of the presence of pellets, there is no mechanical contact.

The boiler bunker filling controller provides automatic control of the fuel level in the feed bunker using capacitive sensors that are not susceptible to dust and mechanical damage. It controls the minimum pellet level and starts the transport device to maintain the operating fuel level. The system prevents downtime by automatically resuming the fuel supply when its level decreases and turning off the transport when there are no pellets.

Converting bakeries to pellets

A capacitive sensor is a device that measures changes in electrical capacitance between two electrodes when an object approaches or contacts them. These sensors respond to changes in the permittivity of the surrounding medium, and are typically used to detect objects, liquids, or changes in material levels.

Their main advantage is high sensitivity, durability and the ability to work with various materials (metals, plastics, liquids). Capacitive sensors are widely used in industry, automation systems, as well as in touch screens of mobile devices and consumer electronics.

Application in heating

Capacitive sensor for heating: advantages

1. Reliable level detection: The capacitive principle of operation allows you to accurately and reliably determine the lack of pellet level in the hopper.
2. Easy to install: Easy integration and configuration ensures quick sensor installation without the need for complex technical knowledge.
3. High accuracy: High-precision measurements guarantee reliable detection of pellet levels, minimizing the risk of possible emergency situations.
4. Durability and reliability: The sensor design ensures long service life and stable operation under various operating conditions.

Modern requirements of ecology and production culture require appropriate solutions, special attention is paid to the cleanliness of emissions into the atmosphere from pellet boilers, An important factor is the possibility of reducing emissions and optimizing the combustion process compared to gas and diesel heating.

The controller with a lambda probe built into the boiler automatically corrects the operation of the pellet boiler pressurization fans or the pellet burner built into the existing boiler, optimizing the fuel combustion process, which, on the one hand, excludes too much air supply for combustion, on the other hand, minimizes the emission of carbon dioxide into the atmosphere, allows not only to reduce the cost of heating by optimizing the fuel/air ratio, but also to ensure a high level of purity in the emission of flue gases from carbon dioxide. In parallel, the controller monitors the temperature of the outgoing flue gases, adjusting the power of the pellet boiler or pellet burner to maintain optimal power, keeping the power at the level of the capabilities of the boiler itself as a heat exchanger, without excessive fuel consumption.

The principle of operation of the controller

The controller corrects the operation of the main control unit of the pellet boiler or burner (ecoMAX 850 and ecoMAX 860), which in turn controls the operation of the fans installed in the boiler and / or pellet burner, while simultaneously controlling the oxygen level in the flue gases. In the case of fan control to correct the level of excess oxygen, the proportions of the primary and secondary blowing of combustion air can be controlled. In case of excess - reducing the proportion and performance of blowing fans, with a shortage - increasing the proportion and performance of blowing fans, trying to maintain optimal performance. During the initial setting, the proportion of excess oxygen and the level of carbon dioxide emissions is optimized using a flue gas analyzer, then it is automatically maintained by the controller independently according to the level of excess oxygen in the flue gases. The power of the pellet boiler or burner is also corrected according to the flue gas temperature. If the temperature is too high, the thermal power is limited, if the flue gas temperature is too low, the power is increased. At the same time, the main control unit ecoMAX monitors the set temperature of the heat carrier and does not allow it to be exceeded, independently limiting the heat output of the pellet boiler or burner, maintaining the set temperature of the heat carrier. As a result, a balanced control system is formed that maintains the optimum output of the heating circuit, automatically maintains the ratio of combustion air to actual fuel consumption and emissions into the atmosphere.
