XCELL BOILER ROOM CASE STUDIES
 

Case Study # 2

Project Installation: Large Insurance Co.; Bloomington, IL
System Design: XCELL Mechanical Systems
System Installation: XCELL Mechanical Systems

The Client
This Insurance Company facility is a 3,000,000 sq. ft. complex which serves as the data processing headquarters for one of the largest insurance companies in the world.
The Problem
  • Wide, seasonal load swings, which created tremendous boiler stresses
  • Recurring Kewanee Phoenix burner head damage and subsequent repair
The Insurance Company's facilities hot water heating system requirements are fulfilled by two Kewanee, firetube boilers, which had experienced recurring burner head failures. This building has tremendously large seasonal load variations which range from 700 H.P. in the cold of the winter, to as low as 69 H.P. in the heat of the summer.
This extremely wide operating range caused a variety of burner and boiler problems which included burner head failures as a result of operating the burners at extremely low firing rates which caused burner head over-heating. Boiler stress as a result of on-off cycling was causing recurring tube and knuckle waterside vessel failures.
Summary : Extremely wide seasonal load swings, boiler waterside vessel failure and burner head overheat failure.
 

XCELL BOILER ROOM SOLUTION
 

XCELL's  Exclusive Portable Burner System

  • The most cost effective solution to the extremely wide seasonal load swings, which are experienced at this and most similar facilities, is to provide burner firing rates which will more accurately match up with system loads.

  • Since building loads regularly approach a 15 to 1 turndown ratio and even the higher turndown burners like the Industrial Combustion D-Series, are limited to a 10 to 1 turndown in firing rate, the answer is to use the portable burner concept, which is exclusive to XCELL Mechanical Systems. Seasonal burner changeouts take about 4 hours and can be performed by in-house personnel.
