The FireMax FMM Series boilers are advanced three-pass fully wet-back steam boilers with an internal furnace design, engineered to deliver reliable steam generation for medium-capacity industrial applications. The integrated furnace configuration allows direct radiant heat transfer from the combustion zone to the surrounding water, significantly improving thermal efficiency and ensuring stable steam generation. The three-pass flue gas flow path maximizes heat recovery by allowing the hot combustion gases to transfer their energy through successive heating surfaces before exiting the boiler, resulting in improved fuel utilization and consistent performance.

In the FireMax FMM Series design, combustion takes place within the internal furnace chamber where fuel is introduced through an automated top fuel feeding system connected to a storage bunker located above the boiler. The fuel transport system can be configured with gravity-fed gates, screw conveyors, scraper conveyors, or belt feeding mechanisms, depending on the fuel characteristics. A forced draft fan supplies controlled airflow into the furnace while the induced draft fan maintains negative pressure inside the combustion chamber, ensuring stable combustion conditions and safe operation.

Efficient combustion is achieved through the controlled distribution of primary and secondary combustion air. Primary air enters through specially designed openings beneath the grate, supporting initial fuel ignition and maintaining the combustion bed. Secondary air is introduced above the furnace to create a swirling flame pattern that enhances mixing between fuel gases and oxygen. This optimized combustion process ensures complete burning of volatile gases, minimizes unburned fuel losses, and significantly reduces the formation of clinker and ash deposits.

Avlon’s FireMax FMM Series boilers are equipped with comprehensive automation, safety interlocks, and auxiliary equipment to ensure reliable and efficient operation. The system includes components such as chain grate stokers, grit arrestors, feedwater pumps, soot blowers, automatic TDS control systems, and advanced control panels for monitoring critical operating parameters. Designed in compliance with Philippine National Standards (PNS) and Department of Labor and Employment (DOLE) safety regulations, the FireMax FMM Series provides industries with a durable, fuel-flexible, and safe steam generation solution capable of supporting continuous industrial processes.
