When it comes to the industrial energy matrix, biomass is increasingly becoming one of Brazil’s most popular sustainable fuels. Ahead of a great potential for development over the coming years, the number of industries that are replacing their traditional fossil fuel boilers with a biomass boiler is increasing dramatically.
However, despite its vast potential for sustainability and environmental responsibility, it is important to remember that the energy efficiency provided by biomass boilers does not come without some operational challenges. This is due to the fact that ash generated during the biomass combustion process has a low melting point, which results in the formation of incrustations that negatively affect the heat transfer process. These formations, which are capable of overtaking the biomass boiler’s grates, piping and walls, can be a big headache for operators.
After all, in addition to reducing the net calorific value of the fuel produced by the boiler, these slags present a high level of hardness, which makes mechanical and manual removal processes more complex and dangerous for those involved. Removal carried out using force can also damage the biomass boiler’s thermal insulation structure, further extending the required repair time.
This is where Bel Mag’s Decrustan comes into play!
Constantly striving to find new sustainable high performance solutions, Bel Mag understands the importance of alternative energy production methods and the reality of companies forced to cope with constant incrustation in biomass boilers better than anyone. Decrustan was therefore developed as an intelligent, conscious, and cost-effective alternative.
A registered trademark since 1975, Decrustan represents a major solution for industries seeking to increase energy efficiency and reduce operating costs. This is due to the fact that, when combined with biomass, Decrustan reacts chemically with ash components during burning, causing them to become soft and loosen, thereby preventing incrustations from forming!
This means that you no longer have to deal with fixed hard slags stuck to grates, piping, walls and the bottom of the biomass boiler. Bel Mag’s solution also acts to neutralize the corrosive acidity of leftover waste gases produced during combustion, thereby reducing wear on the furnace’s internal components.
Ideal solution for enhancing efficiency in biomass boilers
Due to its physical characteristics — a white powder allowing for simple application — and chemical composition, Decrustan diffuses rapidly throughout the interior of the biomass boiler, inhibiting the formation of incrustations by raising the ash’s melting point. In other words, this residual waste can no longer fuse or attach to the boiler’s internal structure.
As a result, this Bel-Mag solution extends equipment life significantly, neutralizing acidic gases and the corrosive effects of ash and reducing operating costs related to maintenance. This is particularly true when we consider the fact that, with the support of Decrustan, the equipment’s energy efficiency is increased by 79% without the need to stop equipment for cleaning.
From there it’s a simple question of numbers: with less interruptions, the generation of energy and steam by the biomass boiler increases significantly. By eliminating the formation of rock-like incrustations, your company is able to guarantee that 100% of the furnace’s energy potential is harnessed and reduce costs associated with the replacement of refractory parts. Isn’t that a beautiful thing?
Decrustan can also be applied through means of automatic or manual dosing and is especially efficient in the day-to-day routines of facilities involved in the production of textiles and cellulose, packaging, and lumber yards that are investing in generating energy through biomass. It is important to remember that the quantity of Decrustan that must be added during the burning process depends on the ash content generated by the biomass. The dosage for each type of biomass is therefore optimized by Bel Mag’s technical team in order to ensure increased boiler efficiency.
We also can’t forget to mention that Decrustan is a magnesium-based product. This means that, when choosing Bel Mag, you are betting on a natural marine-extracted renewable solution that strictly adheres to parameters for sustainability and chemical and environmental responsibility.
