A graphic, and eminently practical book that analyzes plants which use biomass as fuel.

This new book edited by RENOVETEC, distributed in two volumes and dedicated biomass plants focuses on the description of the characteristics of the different types of biomass that can be used in thermoelectric power, the operating principles and equipment that make up a central. Edited in color with a careful layout and an excellent quality of printing, contains almost 460 pages that dealt with a total of 14 chapters divided in two blocks: the first of them is dedicated to biomass and its technical features, while the second is focused in the equipments that make up a thermoelectric biomass plant, their possible configurations and their specific  problems. It also includes over 200 graphics and photographs of actual plants, helping to better understand every concept that is exposed.

What the book does not contain?

As interesting as describing what it contains, it is indicate what does not contain:

  • It is not a generalist book, but it addresses each topic in depth.
  • It is not a basic book, although prior knowledge are not required for understanding all the issues.
  • It is not a theoretical book, but that it is written from the experience of the authors and collaborators in real plants currently in operation or project.
  • Not is a boring book , beacuse those concepts are treated of form pleasant and entertaining.

Book structure:

The book is divided into two blocks:

  • The block 1, that studied the biomass and its features.
  • Block 2, the most extensive, who studies the main equipments that make up a biomass plant and some aspects related to the production of electricity.
