**4. Conclusions**

Using a well-known methodology, it is concluded that the actions actually attacked the root causes that promoted plugging in the biomass system, especially in position M710. The great gain of the work was the low cost and agility in carrying out the proposed actions, surpassing expectations regarding the return that was thought to be possible to achieve. Therefore, the work reached the proposed objective of reducing the occurrences in the power boiler through simple and easy-to-apply solutions, showing that, in general, there are opportunities for solving problems that involve low cost and high return.
