Exhaust Gas Boilers And Economisers working procedure The use of exhaust gases from diesel main propulsion engines to generate steam is a means of heat energy recovery and improved plant efficiency.The auxiliary steam installation provided in modern diesel powered

Exhaust gases from the gas turbine are used to raise steam in the lower cycle without the burning of additional fuel (Fig. 7.3); the temperatures of the gas and water/steam flows are as indicated.

· PDF fileSoot Deposits and Fires in Exhaust gas Boilers 5 Soot Deposits and Fires in Exhaust Gas Boilers Introduction The demand for the highest possible overall fuel efficiency is reflected in de velopments in the propulsion market for oceangoing ships. Today, this market is dominated by highly efficient two stroke low speed diesel engines which run on low quality fuels and utilise (recover) the exhaust gas heat by …

· PDF fileMain engine exhaust gas energy is by far the most attractive among the waste heat sources of a ship because of the heat flow and temperature.

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.

Exhaust gas boilers recover the heat from the exhaust gas of auxiliary diesel heating, where both steam and electricity can be used for heating purposes. Ask Price View More Exhaust Gas Boilers – Marine steam boilers

03-02-2019· Do you mean the one on the exhaust side of the boiler? The idea is to drain any condensation out of the boiler into a bilge tank to avoid it running down and into the main engine turbochargers. If the boiler tubes leak, it’s a handy visual device

09-12-2015· Exhaust gas boiler (EGB or EGE) or economiser described in this article is a smoke tube boiler with steam space, used for heat recovery from main engine exhaust gas. An illustration of the boiler is shown in figure below. The exhaust gas boiler is designed as a vertical boiler with a cylindrical shell surrounding the boiler tubes and water drum as well as the steam space. The tubes consist of a …

Exhaust gas boilers recover the heat from the exhaust gas of auxiliary diesel engines to generate steam and/or hot water, or useful heat for process heating. Depending on system design, these boilers can enhance the efficiency of the auxiliary engine system by up to 20%, leading to lower overall process costs. See Figure 1.
