Biomass Fuel Feed - Handling System

A dependable fuel feed system is crucial to maintaining complete and thorough combustion control in any biomass fired energy system.

Your fuel feed system should be as steady and worry free as possible. EnPlant offers Fuel bin - Live bottom fuel feed System, fuel fed conveyor, intermediate storage bin, fuel feeder. Engineered and designed to work with your furnace and, to deliver the amount of fuel required. Fuel feed system designed for specific HGG ensuring that the energy needs of your plant are consistently met.

Live bottom fuel feed

The Wet Fuel Storage Bin includes rugged live bottom fuel feed design utilizing "ladders" for accurate feed rate control. Ladders have hold down clips on each side. Our ladder design is conservatively designed and capable of handling varying waste wood fuel. The Hydraulic cylinders, motors, and power units for the storage bins are com- pletely external to the bin. The range of fuel storage sizes offered to meet feed requirements and operating schedule of your plant.

Fuel storage

Live bottom fuel system can be silo designed for top-roof loading, side wall open silo design for front loaders and fuel bin for truck unloading.

live bottom "ladders"

This type of silo or bin unloader comprises of hydraulic driven scrapers covering the entire silo bottom. The so called scrapers are built like a climbing Ladder and each foot bar makes the scraper which moves the material forward. The mowing scrapers which we call the "Ladders" are designed in wide and the length is the same as the length of the Bin.

Spike roller – Level roller

Spike roller installed at bin outlet. The purpose is to control the flow of material but also tear apart larger chunks which could cause jamming in the collecting conveyor.

FUEL FEED Drag chain conveyor

EnPlant uses a drag chain conveyor design that uses heavy duty chain to handle hogged bark and other wood waste materials. The Fuel feed conveyor utilizes a bottom drag chain design with the return over top and, comes complete with conveyor chain with flights, gear box drive and motor. The double conveyor chain is running on UHMW rails and, steel flight running on bottom plate Hardox. The Fuel feed conveyor has a tail end sprocket and drive shaft with chain sprockets at the discharge end. Conveyor trough totally enclosed with bolted covers.

Screw conveyor

The screw conveyor is used to transport material from one position to the next. The Screw conveyor is designed for industrial purposes intended for transport of waste wood, wood chips, saw dust horizontally or inclined. The conveyor has a completely welded screw flight on a central shaft of tubing, varying with size of screw diameter and length. The trough is bended and has bolted covers. Rear bearings are foot bearings and, many times equiped with separate packing boxes, front bearings are flange type or foot bearings. Enclosed trough fitted with flanges for inlet and outlet. Gear box drive mounted directly on the drive shaft.

FueL Feeder-metering bin

Fuel is feed into the fuel hopper via the fuel feed conveyor. The integrated fuel pushers are programmed to evenly distribute the fuel onto the furnace Grate front to maintain even fuel pile on the Grate. The Fuel feeder system incorporate hydraulic power pack designed with variable speed capability and, this design gives exact control of the fuel feed to the combustion.

control system

Control systems for biomass fired energy systems are complex due to the integration of fuel handling, combustion control, and ash removal. It is imperative that all of these systems work in harmony together.
