Understanding biomass boilers - Greenhouse Management

Biomass boilers are most common in large-scale greenhouses. Most biomass systems are installed in operations that are 10-acres or larger, says Gene Zebley, renewable energy system sales for Hurst Boiler. Larger facilities can absorb the upfront cost and accept a return on investment (ROI) that stretches for five or six years.

Biomass Gasification - an overview | ScienceDirect Topics

Biomass gasification is used to provide clean gaseous fuel for combustion in furnaces, boilers, and internal combustion engines for power generation and process heating. Biomass in the form of char is usually used rather than in its dried form because the producer gases are relatively free of tar, water, and corroding components.


Hurst Boiler & Welding Co., Inc manufactures its biomass boiler systems with an extended burn chamber, increasing dwell time for the combustion of any unwanted particulates and emissions before they are able to exit the system, making the process much cleaner, which reduces maintenance time and costs.
