Efficiency in boilers and beyond - Alfa Lav

the exhaust gas – not only from the main engine, but from auxiliary engines as well. Energy to push forward Waste heat recovery today is a broader application than ever before, with a significant potential for all vessels. And in a time of slow steaming, it pays to think more broadly. Recovering heat energy from auxiliary engine exhaust, for

Exhaust Gas Boiler on Ships - Marine Engineeri

Dec 09, 2015· In emergency mode the exhaust gas boiler can therefore be operated with low water level and even without water with the full exhaust gas flow through the boiler tubes, provided the boiler is operated depressurised and the inside temperature does not exceed 400˚C. For inside inspection, the boiler is arranged with both hand holes and manholes.

Alfa Laval - Aalborg XS-TC

Aalborg XS-TC7A is an efficient exhaust gas economizer for auxiliary engines. It is designed to significantly reduce the oil consumption for the oil-fired boiler. In the coming years, the marine industry and ship-owners face big challenges as new environmental legislations have special focus on the reduction of emissions from fossil fuels.

Wärtsilä engines auxiliary systems - Wartsila.c

Wärtsilä engines auxiliary systems Some equipment can be built on the engine, and the rest can be delivered separately or grouped in modules. Depending on the engine type and application, lubricating oil pump, HT- and LT-cooling water pumps, fuel pump, oil filters and coolers, pre-lubricating oil pump and thermostatic valves can be built on

Boiler energy efficiency measures - shipboard good practic

As the names imply, the exhaust gas economiser is a waste heat recovery system that recovers heat from exhaust of main or auxiliary engines and thus does not use fuel. The more the second system is used, the less will be a need for use of the auxiliary boilers, thus good maintenance and operating conditions of exhaust gas economiser should

Alfa Laval - Retrofit for Aalborg boile

Retrofit for Aalborg boilers. The waste heat in auxiliary engine exhaust gas contains alarge amount of energy that can be used for steam productionor to generate electricity. Retrofitting an Alfa Laval Aalborgwaste heat recovery system not only lowers emissions andreduces the strain on your oil-fired boiler, but also providesquick return on

Exhaust gas boilers - Ship service syste

The original exhaust gas boilers or economizers were of simple construction and produced, from the low powered engines of the time, a very moderate amount of steam. As large slow speed engine powers increased, the larger quantity of steam that could be generated from otherwise wasted exhaust energy,.. Auxiliary engine Turbo generator

Waste Heat Boilers - Clarke Ener

Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well

Modern Ships Engine Equipment with Waste Heat Recovery Boil

The modern ships engine room equipment includes common rail fuel injection, a waste heat recovery boiler that supplies a steam turbine. The turbine drives a generator that can supply power to motors on the main drive shaft, increasing the efficiency of the plant even more. The exhaust gas emissions of SOx, NOx and particulates are reduced by the use of scrubbers and the efficient engine

Exhaust gas boilers - Clayt

Exhaust gas boilers; Our products are installed around the world, recovering heat from engines, turbines and furnaces. The heat of recovery can be as low as 250 °C (482 °F) or as high as 1200 °C (2192 °F). efficient, flexible and safe means of producing high quality steam or hot water from exhaust gases. Clayton offers a complete

Exhaust gas economizer on auxiliary engin

Exhaust gas economizer on auxiliary engines. A case study of potential savings that can be made by installing an exhaust gas economizer on an auxiliary diesel engine. Diploma thesis in the Marine Engineering Programme . utilize the energy in the exhaust gas with waste heat boilers.
