Numerical Simulation of NO Production in Air-Staged Pulverized Coal Fired Furnace
We describe behavior of the air-coal mixture using the Navier-Stokes equations for the mixture of air and coal particles, accompanied by a turbulence model. The undergoing chemical reactions are described by the Arrhenian kinetics (reaction rate proportional to RT E e ). We also consider the heat transfer via conduction and radiation. The system of PDEs is discretized using the finite volume me...
متن کاملFurnace Wall Corrosion in a Wood-fired Boiler
The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals. These elements increase the corrosion problems at the furnace walls where...
متن کاملMining Temporal Data: A Coal-Fired Boiler Case Study
This paper presents an approach to control pluggage of a coal-fired boiler. The proposed approach involves statistics, data partitioning, parameter reduction, and data mining. The proposed approach was tested on a 750 MW commercial coal-fired boiler affected with a fouling problem that leads to boiler pluggage that causes unscheduled shutdowns. The rare-event detection approach presented in the...
متن کاملCombusting RFO in a Commercial Boiler
Cost-competitive with petroleum fuels Long-term stable price for budget forecasting Made from sustainable, renewable Biomass residuals Storable and pumpable liquid similar to petroleum fuels Clean burning fuel without the sulfur and particulates from petroleum fuels Low greenhouse gas emissions Sustainability issues have become an important part of the supply chain for operati...
متن کاملInvestigations into the Air Heater Ash Deposit Formation in Large Scale Pulverised Coal Fired Boiler
A mineralogical study was undertaken of air heater deposits in a 300 MWe pf boiler located in Western Australia to understand the deposit formation in air heater sections of boiler as an aid to implement possible remediation actions. Several air heater deposit samples were collected in the selected regions of the air heater along with samples of the feed coal, bottom ash and fly ash for compari...
