Every six months or so the majority of steamdriven ships spend a few days in docks having their boilers scaled and cleaned. In the larger docks there are men who are employed full time in this occupation, but elsewhere and in industry generally the cleaning is more often done as an occasional job. The total number of men engaged in the work full time is not large, but the occupation is a very d...

The goal of this project is to develop an technique to measure the PM produced by a two-stage wood based boiler in an inexpensive manner while still preserving high degree of accuracy. The general idea involved in the process involves sampling of the exhaust gas using a vacuum pump. A filter paper with a permeability of 2μm is used to capture PM2.5 present in the exhaust. The sampled data is me...

The fluctuation in temperature and pressure boiler parts subjected to creep fatigue stress also fuel burnt steam generation leads corrosion various areas the boiler. Residual during manufacturing, vibration due flow over tube, mechanical vibrations, erosion abrasive nature of fuel, does occur boilers. All above, individually or combined lead material degradation different magnitude will failure...

In order to maintain the availability of electricity supply, a failure at power plant is mandatory be prevented. If damage has occurred, analysis root cause must prioritized resolve problem and prevent further damage. One important units in boiler that role as steam generator producing by changing water liquid vapor phase. The quality (feed) becomes one crucial factor determining lifetime boile...

The economizers are used for production of steam heating on en route ships. The economizers are producing steam in a heat exchange process from the ship’s main engine exhaust gas. Products of the incomplete combustion of the heavy fuel oil remaining in engines, passing the boiler, collect on the heat exchange surface of the economizer. When the incorrect assumptions are made for the boiler oper...

This paper presents a methodology to simulate the combustion of fixed beds of biomass particles using computational fluid dynamics (CFD) techniques. The models presented were used in the simulation of a domestic pellet boiler working under operating conditions and the model predictions were compared with measurements of heat transfer, temperature and species concentration. The same procedure wa...
