The utilization of waste heat from biomass boilers is a crucial means to enhance energy efficiency and reduce energy consumption and emissions. The following are some common applications and analyses of waste heat utilization technologies in biomass boilers:
Eco-friendly Air Preheater: Biomass boiler combustion produces flue gas rich in thermal energy. The eco-friendly air preheater recovers and utilizes this excess heat, preheating the air entering the boiler to enhance combustion efficiency. Through waste heat recovery, fuel consumption can be reduced and flue gas emissions minimized.
Boiler Economizer: A boiler economizer is a device used to recover waste heat from flue gas. By transferring heat from the flue gas to the boiler feed water, it increases the water temperature and reduces fuel consumption. The application of the economizer can effectively lower the flue gas temperature from the boiler and improve thermal efficiency.
Flue Gas Heat Recovery Boiler: A flue gas heat recovery boiler is a device that utilizes the waste heat from biomass boiler flue gas to produce steam or hot water. By converting the waste heat in the flue gas into usable heat energy, it achieves the reuse of energy and improves the energy utilization efficiency.
Direct Utilization of Flue Gas: The waste heat in biomass boiler flue gas can be directly used for heating or drying processes, reducing the demand for other energy sources. For instance, the flue gas can be transported through chimneys or pipes to the locations requiring heating, and the thermal energy of the flue gas can be utilized directly.
Flue Gas Heat Recovery System: The flue gas heat recovery system recovers and utilizes the excess heat from biomass boiler flue gas to supply other equipment or systems, such as air conditioning, heating, and hot water. This achieves comprehensive energy utilization and improves overall energy efficiency.

Dust removal technology for coal-fired boilers is designed to reduce particulate emissions during the combustion process, protecting the environment and improving air quality. Here are several common dust removal techniques for coal-fired boilers:
Mechanical Dust Collectors: Mechanical dust collectors are among the common dust removal equipment, separating particulate matter from flue gas through physical principles. Common types include gravity dust collectors, inertial dust collectors, bag dust collectors, etc. The working principle of mechanical dust collectors is to utilize the inertia, gravity, or filtering effect of particles to separate them from the flue gas.
Electrostatic Precipitator: An electrostatic precipitator utilizes the force of an electric field to charge particles in flue gas, and then collects the charged particles by the action of the electric field. There are two types of electrostatic precipitators: dry and wet. Dry electrostatic precipitators are suitable for high-temperature flue gas, while wet electrostatic precipitators are suitable for flue gas with high humidity.
Wet Dust Collector: Wet dust collectors utilize spraying water or other liquids to humidify particles in flue gas, and then separate the humidified particles from the flue gas through gravity or inertial force. They are suitable for the treatment of flue gas with high humidity and sticky particles.
Electrostatic Precipitator: An electrostatic precipitator charges particulates in flue gas using an electric field, then collects the charged particles by the force of the electric field. It is suitable for the treatment of high-temperature flue gas and fine particulates.
Dust and desulfurization integrated technology: This technology combines the dust removal and desulfurization processes into one, achieving integrated treatment by sharing equipment and jointly processing flue gas. It can reduce the footprint of equipment, lower investment and operational costs.
Above are common coal-fired boiler dust removal technologies. Different dust removal techniques are suitable for different flue gas and particulate matter characteristics. In practical application, an appropriate combination of dust removal techniques can be selected based on specific circumstances to achieve the goal of reducing particulate emissions.
