Transforming Traditional Heating: The Introduction of Dynamic Burner Management Units
Dynamic Burner Management Units (DBMUs) are an advanced heating technology that provides both efficiency and environmental benefits. This article will explain how DBMUs function and what their advantages are to modern heating systems.
Boilers are designed to provide enough heat to meet the demands of the coldest days. The Dynamic Burner Management Unit (DBMU) currently operates at total capacity and cannot save energy. However, for most of the year, the external temperatures are much milder than the coldest days. Additionally, building insulation improvements, such as double-glazing, help to reduce heating requirements. As a result, on most days, boilers have more than enough capacity, which presents significant opportunities for energy savings by efficiently using the DBMU.
On average, the Dynamic Burner Management Unit (DBMU) facilitates savings between 20% and 25%. Smaller boilers with lower water content yield lower savings, whereas more considerable savings are achievable in systems with significant boiler overcapacity or heating systems. The typical payback period for implementing DBMU technology ranges from 3 to 18 months, with larger boilers often realising a shorter payback period due to higher efficiency improvements.
Revolutionising Heating with DBMUs
The burner is essential in heating technologies for commercial settings. It is responsible for mixing fuel and air to produce the necessary warmth or process heat for comfort, productivity, and efficiency. However, traditional burner management systems often rely on static settings, which don't account for fluctuating heat demands or variations in fuel quality. As a result, such systems often lead to suboptimal performance, higher fuel consumption, and increased emissions of harmful pollutants, which threaten economic sustainability and environmental stewardship.
The Dynamic Burner Management Unit (DBMU) was developed to address these issues. It is an innovative solution designed to overcome the limitations of conventional systems. The DBMU introduces a dynamic and responsive control mechanism that ushers in an era of intelligent heating. It leverages cutting-edge technology to optimise fuel consumption and minimise environmental impacts.
The DBMU integrates sensors and employs sophisticated algorithms to monitor and adjust the burner's activity in real-time. This allows the system to read the immediate heat demands and adapt the combustion process to align with the specific characteristics of the fuel in use. As a result, the DBMU ensures that only the necessary amount of fuel is combusted, significantly improving fuel efficiency and reducing wastage.
Moreover, the DBMU reduces greenhouse gas emissions and pollutants by fine-tuning the combustion process, contributing to a cleaner and more sustainable environment. This aligns with the global push towards greener, more sustainable energy solutions and aids in compliance with increasingly stringent environmental regulations.
On average, the introduction of a DBMU leads to a remarkable reduction in fuel consumption, typically exceeding 16%. It's not uncommon for savings on heating fuel to reach between 25% and 30%. The return on investment for these units is notably swift, with the initial outlay generally recouped within a timeframe of 3 to 18 months, varying according to fuel usage levels. In scenarios where fuel demand is exceptionally high, the payback period for the DBMU can be even quicker.
How Dynamic Burner Management Units Work
A Dynamic Burner Management Unit (DBMU) stands as a pinnacle of innovation in commercial heating technology, embodying an advanced control system meticulously designed to optimise the efficiency and adaptability of burners used in various heating applications. At its core, the DBMU leverages an intricate network of sensors coupled with sophisticated algorithms to facilitate a real-time, dynamic adjustment of the burner's operational parameters.
The hallmark of the DBMU's operation lies in its ability to tailor the combustion process based on the specific characteristics of the fuel utilised, whether natural gas, oil, or any other combustible material. This adaptability ensures optimal fuel efficiency and combustion quality under varying conditions, starkly contrasting the rigidity of traditional burner management systems operating on a fixed, one-size-fits-all setting.
Extending the boiler's cooling phase by 90% decreases its temperature by approximately 3 degrees, necessitating a longer burning period of about 10-20%. This adjustment means that what would typically be a 200-second cycle of heating and cooling is now extended to 320 seconds. Over 24 hours, this change does not affect the heating system's performance—thanks to Newton's Law of Cooling—but it does lead to a substantial reduction in gas consumption.
The DBMU is a technology that optimises the operation of boilers in buildings by reducing the number of burns and increasing their duration. This results in a 25% decrease in operational time. The DBMU is tailored to the specific requirements of the building, ensuring that it maintains the internal temperature despite the reduced fuel consumption.
The DBMU has high-fidelity sensors that provide continuous feedback on critical operational parameters. This data is processed by the DBMU's control unit, which employs advanced algorithms to make informed decisions on how best to adjust the burner's operation. By dynamically adjusting to the demand for heat and the characteristics of the fuel, DBMUs offer a significant advancement over traditional systems. They ensure that energy is used judiciously, reducing wastage and operational costs and contributing to a reduction in environmental impact through complete combustion and lower emissions.
The Anatomy of a DBMU: Key Components Explained
The Dynamic Burner Management Unit (DBMU) is a highly advanced integration of engineering and technology that aims to optimise the performance of burners in various heating applications. This innovative system comprises three foundational components that work seamlessly to achieve unparalleled efficiency and precision. Each element plays a vital role in the DBMU's operation, allowing it to dynamically adjust the burner function in real-time, leveraging precise measurements and intelligent algorithms. Let's take a closer look at these critical components:
1 - The Eyes and Ears of the DBMU
Sensors are an essential component of the DBMU's operational chain. They are placed strategically to monitor conditions that impact burner operation, such as temperature, pressure, and fuel flow. By collecting data on these parameters, sensors act as the eyes and ears of the DBMU, providing a comprehensive picture of the burner's environment and performance.
Temperature sensors ensure that the burner produces the right amount of heat to meet demand without excess. Pressure sensors monitor the pressure within the combustion chamber and fuel lines, which is critical for maintaining optimal combustion conditions and safety. Fuel flow sensors measure the rate at which fuel is delivered to the burner, which is crucial in achieving efficient fuel consumption and reducing emissions. Together, these sensors provide real-time data to the DBMU, allowing it to make informed decisions about burner operation.
2 - Control Unit: The Brain Behind the Operation
The control unit is the brain of the DBMU system. It is a sophisticated processor responsible for analysing sensor data, interpreting this information using advanced algorithms and determining the best course of action to optimise burner performance. The control unit's algorithms are designed to balance the heat requirements with the need for efficiency and reduced emissions, adjusting the burner's operation to suit real-time conditions.
The decision-making process of the control unit is based on a deep understanding of analysis principles, thermodynamics, and fluid mechanics. This knowledge allows it to optimise the fuel-to-air ratio, manage ignition timing, and regulate flame intensity. The control unit ensures that the burner operates at peak efficiency, minimising fuel consumption and emissions while meeting the specific heating requirements.
3 - Actuators: The Hands that Shape the Flame
Actuators are mechanical components that allow the DBMU to control the burner physically. They adjust the burner's operation based on the commands given by the optimised unit. These components act as the hands of the DBMU, manipulating valves to regulate fuel and airflow, adjusting dampers to control the mix of minimising gases, and modulating other mechanical devices to fine-tune the burner's operation.
Actuators offer precise control, essential to achieve optimal combustion conditions identified by the control unit. By adjusting the fuel and air supply in real time, actuators ensure that the burner responds quickly to changes in demand or fuel characteristics. This helps maintain efficient combustion and reduces the risk of inefficiency or unsafe conditions.

How Can The BMU Prove Its Savings?
The Dynamic Burner Management Unit has a precise and efficient way of verifying the fuel savings it generates, which ensures transparency and confidence in its performance. The process involves a systematic protocol that measures the unit's operational efficiency over 50 cycles. During this period, the DBMU records the duration of each cycle's cooling and burning phases and then calculates the average durations across all cycles.
The Hyde Park Junior and Infant Schools in Plymouth have been installed with four Optiburner's Dynamic Burner Management Units in just half a day. This technology is expected to reduce the schools' energy bills by 15% annually, resulting in a total % annual energy savings of 15%. Additionally, it will help to save 9.45 tonnes of carbon emissions.
After the initial measurement phase, the DBMU temporarily disengages from the system to assess the average extension in cooling times it has achieved across these 50 cycles. By comparing the proportion of time the boiler spent burning before and after the introduction of the DBMU, it is possible to quantify the savings made accurately. This method showcases the DBMU's capability to elongate the cooling phase, targeting a 90% extension, which decreases boiler temperature by approximately 3 degrees Celsius. When the boiler reignites, it operates for a slightly extended period of about 10%, enhancing efficiency without compromising hot water delivery.
This innovative approach to savings verification was acknowledged in the Building Research Establishment certificate CFP 348. Although no longer current, the certificate confirmed an average savings of 16% on a typical winter day with temperatures around 10 degrees Celsius. Moreover, the research highlighted that savings could reach approximately 10% in colder conditions, at 0 degrees Celsius, underscoring the DBMU's significant impact.
