In the marine steam power plant, the main boiler has the small size and the little heat capacity. However, marine ship requires high maneuverability, when it is running, the loads varied frequently, and the varying range is big, and this will cause the boiler security problem, such as over-pressure or under-voltage. The marine steam power plant boilerturbine coordinated control strategy is to s...

Pulp and paper mills are high power consuming industries. Pulp and integrated mills produce power via steam turbines in recovery boilers. Due to high power prices and the fact that biomass combusted in the recovery boiler is considered as green energy, there is today a desire to always increase the power generation when investing in new recovery boilers. In order to increase power output from t...

Performance of a fuzzy system identifier is investigated against a fossil fuel boiler data. A multi-layer neuro-ftrzzy system presents identification of a drum type boiler. This identification techruque provides a rule-based approach to express the boiler dynamics in fuzzy rules that are generated from the experimental boiler data. The interconnections of neuro-fuzzy layers furnish these fuzzy ...

this paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. there are 12 feed pu...

Palm oil is one of the two most important vegetable oils in the world’s oil and fats market. The extraction and purification processes generate different kinds of waste generally known as palm oil mill effluent (POME). The environmental impact of POME cannot be over emphasized; hence the need for treatment measures to reduce these impacts before discharge. Therefore, this paper reviews the proc...

Palm oil is one of the most important agroindustries in Malaysia. Huge quantities of palm oil mill effluent (POME) pose a great threat to aqueous environment due to its very high COD. To make full use of discharged wastes, the integrated "zero discharge" pilot-scale industrial plant comprising "pretreatment-anaerobic and aerobic process-membrane separation" was continuously operated for 1 year....

Conversion of water into steam is the primary function of a utility boiler. The steam pressure is used to turn a steam turbine thus, generating electricity. Within the boiler drum there exists a steam/water interface. Boiler steam drum water level is one of the important parameters of power plant that must be measured and controlled. For safe and efficient boiler operation, a constant level of ...

Fouling and slagging are some difficulties for the development of biomass as energy potential and to achieve the targets of renewable energy sources utilization. The proper technique to analyze the influence of fouling in a biomass boiler is to monitorize the evolution of heat absorption in heat transfer equipment. Traditional equation-based monitoring techniques have problems to tackle with th...

Studies on the durability and dimensional stability of a series of hardwoods and softwoods after thermal modification in vegetable oils and in steam atmospheres have been performed. Mass loss after exposure to Coniophora puteana (BAM Ebw.15) for 16 weeks was very low for European birch, European aspen, Norway spruce, and Scots pine thermally modified in a linseed oil product with preservative (...

The ratio of furnace bottom ash (FBA) to flyash produced in a coal-fired boiler was historically around 25:75 with utility boilers operating with an unstaged combustion regime. With the advent of low NOx burner systems this ratio has changed and is now 15:85 or even lower. This is unfortunate since the demand for FBA is high, with 100% of is sold to the construction industry, whereas only 50% o...
