Several processes in the industries require heat. Nowadays, many industries rely on pellet burners for meeting their heat requirement. The pellet burners were a perfect replacement for diesel burners as they were compatible with the existing system and helped the consumers to reduce their fuel cost by up to 50%. As a result, there was a massive transition of industries from diesel to pellets. Initially, the prices of pellets were low, and customers were okay to pay for that. But pellets now cost almost twice what they used to cost a few years back, and businesses aren’t happy with that. So, customers are again looking for cost-effective alternatives, which led to the evolution of Steamax’s Multi-fuel burner (MFB). 

MFB is designed to accommodate a greater variety of biomass fuels than the standard pellet burners which help customers to reduce their carbon footprint and fuel costs.

Why Pellet Burners Are Slowly Fading Out?

Pellet burners are designed only to burn pellets of specific sizes and materials. For example, most pellet burners are compatible with only sawdust pellets of dia 6-8mm. Due to its design features, other fuels cannot be burned efficiently in these pellet burners. Here are some of our observations:


1. The burner and hopper are designed not to let any other fuel be fed into the system. The feeder will stop working if pellets bigger than 8mm are fed in the system due to the smaller pitch and screw diameter.


2. The burner is designed to keep the screw conveyor and burner nozzle the same height. If any other small size fuel is added, it will throw fuel directly to the nozzle from the conveyor, which leads to an increase in the carryover of unburnt fuel particles.

Our Approach

We always believe that flexibility is a great thing. Binding customers with a specific fuel is not the right approach. Customers should have the right to choose their fuel. So we came up with a flexible design to use other fuels in our MFB.


  • We improved the hopper angle to allow free flow of materials like dried wood chips, walnut shells, Astillas, etc. which has high wall resistance.


  • The diameter and pitch of the feeder were increased to compensate for the low bulk density of other fuels.


  • We created a new biomass fuel blend, Astillas, with a high calorific value than pellets and is cost-effective.


  • The burner nozzle centre height was increased to avoid carryover of biomass.


How Different Options Can Save You Money?

The biomass prices are fluctuating, and it is wise is to choose the burner that can effectively utilize different biomass fuels. As it goes, “Having only one option is not an option”.
