Boiler Stack Gas Heat Recovery ABSTRACT This report is a detailed study of various heat recovery schemes for Navy shore facilities to utilize otherwise lost stack heat. The waste heat can be used alternatively to improve the boiler efficiency through feedwater and/or combustion-air preheating, or to lighten the boiler load through
Ships thermal oil boilers: Three-pass forced circulation heaters with tube coil for heating thermal oil. These boilers are used onboard ships and on off-shore rigs. The design of these boilers is aligned with the restricted spatial conditions, vibrations and movements of the ship. BBS ships boilers can be configured as composite boilers.
The revolutionary switch from traditional to condensing boilers in the heating market that has occurred over the past 10 years is due to the desire to reduce carbon output. In steam systems, the development and adoption of advanced materials and designs of heat recovery stack economizers is also due to a desire to reduce carbon output.
Application The waste heat recovery unit recovers thermal energy in the waste heat from the gas turbine exhaust gas, enabling generation of hot water, saturated steam or superheated steam. The WHRU is also capable of heating up thermal oil and TEG, and can be designed to fit individual customer needs and optimum performance.
The heat from the boiler can be used for this. For example: The steam from the boiler goes to the turbine, after the turbine the steam is still a little bit superheated and can be used to heat up the flue gas in the chimney. This is a cogeneration system, a combination of electricity and heat is recovered from the boiler. Conclusion and some examples:

Heat recovery boilers are also often found in association with high temperature processes such as steel and glass making. It is not uncommon for these boilers to receive additional heat by supplementary firing of other by-products or by burning gas or light oil to raise the boiler inlet gas temperature to a level commensurate with the desired steam conditions.
From waste to win. The recovery of waste heat is a unique opportunity that benefits operating economy as much as it does the environment. With as much as 35% of an engine’s fuel energy going into the exhaust flow as waste heat, there are substantial savings to be made when that energy is recovered.
Waste Heat Recovery. With the high cost and environmental impact of fossil fuels, heat energy is a precious commodity that cannot be wasted. Any exhaust gas stream with temperatures above 250°F has the potential for significant waste heat recovery. Consumers of waste heat energy can be found in almost any facility and are easy to locate.
Boilers are another type of oil heater. While furnaces heat air, hydronic boilers warm up water. The liquid travels through the house, providing heat through equipment such as radiators or baseboards. Cooled water then cycles back to the boiler for reheating.A less common oil heater is a steam boiler.
The concept of Waste Heat Recovery. To ensure the most advantageous design, the WHR boiler concept will be specially tailored to the individual ship and engine design with due consideration of existing uptake back pressure, etc. The concept comes in two designs: one that requires a steam space in another boiler (e.g.
Heat recovery boilers are thermal machines that employ the heat of exhaust gases to produce hot water, superheated water or steam. Traditional recovery boilers do not have a furnace, as the water inside them is not heated up with a burner, but just with the heat of fumes conveyed in them.
A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally. Boilers like this have been widely used on ships as either auxiliary or donkey boilers.
Advice on waste heat recovery in industrial applications. A waste heat recovery unit/heat exchanger recovers heat from hot streams, water or gasses, that still have a relatively high energy content which would otherwise go unused into the atmosphere.
a waste heat recovery system compris-ing both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler feed-water heating. This paper describes the technology behind waste heat recovery and the potential for ship-owners to lower fuel costs, cut emissions, and the effect on the EEDI of the ship. Introduction

Different types of energy recovery systems for waste incinerators, thermal oil systems, steam boilers with turbines or air-air heat exchangers Photo 1: Example of a steam system Types of energy recuperation for incinerators The heat recovery of a waste incinerator we call just heat recovery system.
Fuel is burnt in the engine. And the exhaust goes out of it. Although the energy from fuel released in the engine is already used by the engine, but the heat is still there in the exhaust. Now this heat in the exhaust can be used to heat the water and generate steam. Here we are talking of big engines which might be having more 5 units.
We have already manufactured and delivered various kinds of our waste heat boilers, and its number has reached about 100. Our waste heat boilers can meet the demand and requirement of customer, and we can sell them with confidence. 1. Possible to run without decreasing its efficiency for a long period, as its heating surface can keep off dirt. 2.
“The cost of waste heat recovery systems could be $5 to 6 million dollars but if you take a long outlook life cycle analysis we do see that you get [to recover] the minimum payback value.
Cannon Bono Energia’s range of waste heat recovery steam generators are used for steam production or energy generation utilising the waste heat from gas turbines, medium speed diesel engines or recovering the waste heat of some industrial processes.

Good applications for heat to power installations include reciprocating engines, biomass boilers, turbines, and other industrial processes Heat produced by the applications is captured in exhaust streams, water, or steam processes and transferred to the Clean Cycle solution.
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 always be regarded as part of energy saving in the steam system.
This results in less fuel being used by the burner to generate steam. Waste heat from other sources such as diesel engines or gas turbines can also be used to pre-heat boiler feed water. 2. Waste heat boiler (WHB) or exhaust gas boiler (EGB) – a stand-alone unit is used to create steam without the need for a separate boiler.

Instead of wasting the heat, the boilers and heaters for heat recovery offer very good opportunities for utilising the waste heat for production of steam, hot thermal oil or hot water. Today process heat recovery offers substantial economical advantages - due to reduction of CO2 and saving the fuel.
RE: drum boilers for thermal oil recovery process davefitz (Mechanical) 22 Sep 09 13:47 I am not familiar with the pricing of the IST OTU , but if it is made of 100% incolnel and the drum boiler ( sat steam) is 100% carbon steel, then the cost difference is likely the material cost difference of CS vs incolnel.
Operational can recover heat from the kiln exhaust air and transfer the recovered heat via a thermal oil circuit to heat exchangers installed in the dryer air recirculation systems. Operational use specially constructed finned and plain tubed air to thermal oil heat exchangers together with a high temperature thermal oil pipework system.
heat recovery is to capture the waste heat streams and transfer the heat into useful energy. The advantages to the industrial processor are that waste heat recovery can reduce a facility’s annual fuel bills, reduce plant emissions and improve productivity. In process heat-ing, using waste heat saves fuel or electricity that would otherwise be pur-
