Turndown ratio? — Heating Help: The Wall

OK, I'm confused by all these turndown ratio claims. Some boiler manufacturers claim 20:1, some now claim they can do 10:1, while the majority have stuck with 5:1 turndown. I've even heard the mfgrs that claim high turndown ratios actually ship them to the jobsite with 5:1 ratio, and then rely on the startup technician to change it upwards

Turndown ratio - WikiMili, The Best Wikipedia Reader

2020-1-23 · Turndown ratio refers to the width of the operational range of a device, and is defined as the ratio of the maximum capacity to minimum capacity. For example, a device with a maximum output of 10 units and a minimum output of 2 units has a turndown ratio of 5. The term is commonly used with measurement devices and combustion plant like boilers and gasifiers.

Combustion System of a Reheating Furnace – IspatGuru

The main function of a reheating furnace is to raise the temperature of the semi-finished steels (billets, blooms, slabs or rounds) typically to temperatures between 1000 deg C and 1250 deg C, until it is plastic enough to be rolled to the desired section, size or shape in the hot rolling mill. The reheating furnace must also meet specific
