Before you start raising the level in the boiler you have to find out if any part of the furnace walls has been overheated. If you raise the level over a glowing steel-wall then the boiler might produce more steam than the safety valves can handle and a nasty explosion would be the result. Boiler Questions and Answers

Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.
In a boiler trial the temperature of the feed water is 60 degrees Fahrenheit and the pressure under which steam is delivered is 160.3 pounds gauge pressure or 175 pounds absolute pressure. The total heat of one pound of steam at 175 pounds pressure is 1195.9 B. t. u. measured above the standard temperature of 32 degrees Fahrenheit.
Cupric oxide particles were separated into three fractions, clumps, short rods and long; and 5 mg/kg live weight of each fraction given to steers of 173 kg mean live weight. The form of the particles did not affect either their retention in the alimentary tract or the accumulation of copper in the liver. PubMed Abstract
The Basics of Steam Generation - 4 A simple boiler In order to describe the principles of a steam boiler, consider a very simple case, where the boiler simply is a container, partially filled with water (Figure 1). Combustion of fuel produce heat, which is transferred to the container and makes the water evaporate. The vapor or steam

The mass won't change, so 1 kg of liquid water will form 1 kg of steam. Taking the density of water to be 1 g/cm³, you need 1 L of water to produce 1 kg of steam (in actual fact, you need a bit more, since water is not quite that dense). To make 1 ton of steam, assuming you use a metric ton, you need 1,000 L of water.
