How do you justify the replaceability of a vintage boiler?
It shouldn’t be forgotten, that the cost of fuel running your boiler may have already changed in several folds after installation. It is likely so to have increased fuel cost bills at least 2-5 times, or even more, depending upon the span of time that had elapsed, since you first installed your boiler unit. An efficiency lost factor therefore of 5% must have multiplied also by the same number of folds, over the years in terms of energy cost, and if it’s a large consumer of fuel, then you better assess now and evaluate again those cost of operational inefficiencies, as it could certainly justify the investment of getting a more efficient boiler. A newer boiler could be specified to fit better the actual consumption for steam in your facility. It can also have better control systems and mechanisms to make air to fuel ratios more consistent. A very large boiler serving the needs of a small demand load is highly inefficient, in terms of start up cost, cycling cost, and heat losses by radiation due to large surface area exposure also. Try doing your pencil pushing in this regard. You may save your firm a fortune today and ride better, the tide of a fast changing business landscape. Ask outside help if you must. Just save energy and help your operational profitability improve your company bottom-line.
