Boiler Fuel - an overview | ScienceDirect Topics

Boiler fuel control then follows the turbine control to raise the throttle steam pressure to its rated value. Throttle governing is the most favorable method of control in the above two modes. Figure 6.46 shows the "main steam pressure vs. load" characteristic of "constant pressure", "true sliding pressure", "modified sliding pressure" operations.

Boiler Operation & Boiler Maintenance | HSB Locomotive

Every steam and hot water heating boiler must have at least one safety or safety relief valve of sufficient relieving capacity to meet or exceed the maximum burner output. The ability of a safety valve to perform its intended function can be affected by several things, such as internal corrosion or restricted flow, which can prevent the valve from functioning as designed.

Turndown ratio - Wikipedia

If a boiler application requires it to operate at a low proportion of its maximum output, a high turndown ratio is required. Conversely, in applications where the operational conditions are not expected to vary significantly (for example, a large power plant), a low turndown ratio will be sufficient.
