The fuel-to-steam efficiency of a boiler is the ratio of BTU (British thermal unit) output divided by BTU input, with the input being the fuel used to power the boiler and the output being the steam generated by the boiler. The higher the fuel-to-steam efficiency, the more steam you get compared to the fuel needed to create that steam. In essence, the higher the boiler efficiency rating, the more steam you get for your dollar. With the rising cost of fuel and the many incentives to lower your fuel usage, there is a great incentive for facilities that rely on industrial boilers to maximize their fuel-to-steam efficiency as much as possible as a way to cut costs.
Miura has become one of the best companies manufacturing boilers with high fuel-to-steam efficiency. The EX and LX models of Miura’s water tube boilers have a fuel-to-steam efficiency rating of 85%. Whereas the average fire tube boiler only offers 83% fuel-to-steam efficiency. That may seem like a small difference, but a 2% difference in efficiency creates fuel cost savings between 10 and 40%. Most facilities that switch to Miura boilers from conventional fire tube boilers report saving roughly 20% on fuel and energy after making the switch.
Many factors are important to weigh when deciding on a new industrial boiler. However, fuel-to-steam boiler efficiency is not something that should be overlooked. Finding a boiler that excels in this area can go a long way toward saving on operating costs with your new boiler.
