1. Upgrading of Boiler exhaust system Presentation Holiday Inn Bahrain Feb 2002

2. Boiler exhaust ducting 4 Present Situation: 4 This image shows the boiler chimney at Holiday Inn 4 Image taken during this week.

3. Boiler Exhaust ducting 4 It is not a good scene.Isn’t it? 4 Why this thick smoke? 4 Is there a fire..!!

4. Boiler Exhaust ducting 4 No.. It is not fire.. 4 The smoke is from the Boilers that are working hard to provide steam and hot water to the hotel. 4 But Why it should make this much black smoke?

5. Boiler Exhaust ducting 4 The picture here shows the boilers in the basement. 4 Boilers are producing steam and hot water for use in rooms, kitchen and laundry.

6. Boiler exhaust ducting. 4 Boilers are using diesel for producing steam/hot water. 4 In a normal case the flue gas exhaust is mixture of carbon di oxide and nitrogen. 4

7. Boiler exhaust ducting 4 But if the combustion is incomplete then the flue gas exhaust will be mixture of soot and carbon monoixde which we see in this case. 4 This occurs due to fluctuation in the steam demand and occasionally the exhaust will be thick black smoke as we see in earlier.

8. Boiler Exhaust ducting. 4 At present the flue gas from boilers is discharged to the atmosphere WITHOUT any further treatment. 4 This poses two major problems..

9. Boiler Exhaust ducting 4 It spoils the exterior walls leaving stains on the façade.

10. Boiler exhaust ducting 4 Flue gases are going to stain the new façade that is being provided as part of the current project under construction. 4 Also it is an environmental concern.

11. Boiler exhaust ducting 4 Discharging the smoke is also an environmental issue. 4 Holiday Inn Property director Mr.Steven Jones has made an observation regarding this in his last visit to bahrain.

12. Boiler exhaust ducting 4 How to overcome this problem? 4 We can provide a soot arrestor which works like a filter and reduce the carbon content in the flue gas exhaust. 4 Relocate the chimney to a new location that will not an eyesore.

13. Proposed arrangement of exhaust ducting

14. Closer view of Soot Arrestor

15. Boiler exhaust ducting 4 Scope of work briefly, 4 Introduce new stainless steel ducting and soot arrestor to contain the soot. 4 The soot will be washed away with water and discharged to a special soak pit. 4 Necessary structural and architectural modifications will be incorporated.

16. Boiler exhaust ducting 4 Picture shows the external façade of the boiler room. 4 It is proposed to incorporate the soot arrestor in this area and it will be treated architecturally.

17. Boiler exhaust ducting 4 Although the soot arrestor will reduce the magnitude of the smoke problem, it is very important to ensure the boilers are well maintained. 4 With the soot arrestor and proper maintenance of boilers the present problem of smoke emitting from the boiler chimney can be avoided.
