What does steam consumption rate mean?

[LeGenesis]

Steam consumption rate refers to the amount of steam consumed per kilowatt-hour of work produced. Below are the specific details about steam consumption rate: 1. Unit: The unit of steam consumption rate is kg/kW·h, denoted by d, where d=D/N, with D being the main steam flow and N being the electrical power output of the unit. 2. Calculation formula: Steam consumption rate = main steam flow × 1000 ÷ power generation, with the rated steam consumption rate being 3.025 kg/kW.h. The main steam flow is an accumulated figure over a day or a shift. The instantaneous main steam flow seen on the DAS screen is not measured directly but calculated using the formula: main steam flow G = (PⅠ² - P high exhaust²)^0.5 × 81.9 × 540 ÷ superheater outlet temperature.
