A Standard of Excellence that sets Miura apart from other Process Steam Boiler manufacturers
In-Service Efficiency is a measure of overall performance, no matter your load profile. High In-Service Efficiency is the level of performance every Miura Boiler customer can expect. This standard of excellence has been established based on taking all factors of the boilers operation into account (see chart below). For a further explanation, let’s review the common Definitions of Efficiency as related to the boiler… Miura has developed the term “In-Service Efficiency” to describe:
and defines it as follows: The resulting efficiency of a boiler when the total operation cycles are taken into account such as day, night, weekends, high loads, low loads, standby loads.
Combustion Efficiency Measurement
This is the ratio of BTU output divided by BTU input on a particular boiler. This includes all the heat loss (e.g. radiation and convection losses) from a boiler and is typically used in a manufacturer's catalogue. Fuel-to-steam efficiency is a readily verifiable number and is often used in efficiency guarantees by various manufacturers. It is the ideal "Fire-rate" efficiency, which is tested for about 10 minutes with a stack analyzer. Miura does not think the above efficiencies explain "real-world" efficiencies. Each boiler runs under different operating conditions such as load, operating time, radiation heat losses from boiler physical surface area and so on.
