AMBITIONS The furnace is alight and the feed is running: why the future is bright for biomass CHP plants


iomass combined heat and power plants (BMCHP) produce electrical energy from biogenic solids – and additional heat that


systems for storing, dosing and conveying the diff erent material for this purpose. T e machine builder tailors and matches these systems to the particular application – for example, at Burmeister & Wain Scandinavian Contractor, Vecoplan has designed fuel charging and processing systems at fi ve sites for the Danish manufacturer and BMCHP operator.


In BMCHP, untreated wood chip,


mature timber, agricultural waste and cut branches are incinerated in boilers at over 1,000°C to heat water. T e resulting steam drives a turbine that is coupled to a generator to produce electricity. Some steam is left over and is used to heat water for district heating by means of a heat exchanger. T e energy of the biomass is


The boiler is charged by means of drag chain conveyors
