Protective coatings with combined monitoring system to control process conditions in boilers

Objective

The incineration of waste and combustion of biomass is growing rapidly both due to the environmental aspects (minimisation of landfills, utilisation of waste, reduction of greenhouse gases), and ambition to self-sufficiency of energy sources in European countries (vs. imported oil, coal and gas). However, co-combustion, burning different fuels together (including fuels such as waste, biomass, oil, coal), produces more complex and hard to control combustion process than traditional fuel combustion. The new, harsh condition affects detrimentally onthe boiler construction, i.e. boiler tubing, shortening the lifetime by erosion and corrosion. Hence the control of the burning process, control of emissions, and the safe and long-life use of boilers is becoming more important. To gain efficient control and reliability of boilers, new methods and protections have to be applied. In the proposed work a novel approach to both monitor the temperature of boiler and protect the susceptible boiler construction is introduced. The main innovation is to combine a protective coating and temperature monitoringoptical fibre by developing a novel temperature monitoring protective coating. Hence less polluting and long-lasting boilers, which are able to burn reliably fuels like waste and biomass, are achieved. A novel combination of a protective coating and temperature monitoring will be achieved with co-operation of different European SME's. The project gives an opportunity to combine two different technologies. Both the best know-how concerning novel monitoring technology and latest knowledge of the protective coatings is in SME's and located in different countries. The technological and economical chain is formed by coating manufacturer PikoBlade (FI); ART Photonics (G), industrial manufacturer of optical fibres; coating manufacturer Flame Spray (IT); Hitele Systems (UK), DTS (distribute temperature sensing) company (UK); and coating raw material distributor DURUM (G).
