Disadvantages of shell boilers: The package principle means that approximately 27 000 kg/h is the maximum output of a shell boiler. If more steam is required, then several boilers need to be connected together. The large diameter cylinders used in the construction of shell boilers effectively limit their operating pressure to approximately 27 bar.Learn More
There are several methods, which can be used for measuring heat output. With steam boilers, an installed steam meter can be used to measure flow rate, but this must be corrected for tem-perature and pressure. In earlier years, this approach was not favoured due to the change in 1. Energy Performance Assessment of BoilersLearn More
