How gasification CHP works

How gasification CHP works

The Process

The CHP units we supply; Froling and Spanner, work by drying and burning untreated woodchip to create a combustible gas.


The gas is cooled and cleaned, then injected into an engine to produce electricity.


Heat from the engine, flue gas and wood gas is recovered and, along with the electricity, is used on site.



CHP is reliable


Each CHP unit can provide a continuous supply of up to 104kW of heat and 50kW electricity.


This is ideal if you have a significant year-round demand for heating and power.


CHP is good for the environment

Wood chip is a renewable, carbon neutral fuel.  So switching to CHP means you can cut your CO2 emissions and receive an income from government incentives.


Switching to CHP – what’s involved

CHP is easy to install and with one of our servicing plans will run reliably for many years.


However, to make sure you get the best return on your investment it’s important you install the right unit for your needs, have it serviced regularly and use high-quality fuel. We can help.



  • Design a unit that will best suit your site and energy needs
  • Supply, install and commission the unit
  • Provide on-site training
  • Provide off-site monitoring in conjunction with Froling
  • Provide telephone and on-site support
  • Service the unit under an annual contract

CHP is efficient

CHP is efficient because it retains more of the energy it produces than standard power plants.


Higher quality fuel = higher returns

To get the best return from CHP you must use a good quality fuel. Softwood is better than hardwood and the chip must be as dry as possible. As a minimum it should be:

  • <10% moisture content
  • G50 size with minimal fines


Drying your own wood chip

We can connect the heat recovered from your CHP unit to a dryer. Then, if you produce your own chip or buy it in wet, you can dry it on site.

Free Site Survey

To provide you with reliable and cost-effective energy CHP must meet a number of legal, technical and site considerations.


We can survey your site to make sure switching to CHP will work well for you.


There’s no obligation and it’s completely free.

Connecting to the public electricity supply

The local distribution network operator (DNO) must give permission for a CHP unit to connect to the public electricity supply.

They may need to assess the impact of the unit on the network and may stipulate design and operating requirements, securing their permission can be a complex process.


We can help make this quicker and easier. We know the DNOs in our local area well and have worked with their staff so often we’re on first name terms with many of them.
