suijitupian9.jpg" />Apr 30, 2019 · In order to size a steam boiler, a heating contractor must determine the square foot of radiation connected to the steam system. This process is called an equivalence of direct radiation (EDR). First, each radiator in the home must be measured: height, length and width. Once the volume of all radiators is known, a boiler can be selected
suijitupian58.jpg" />No wonder lazy heating engineers push the combi boiler heating system in preference to a proper boiler and hot water cylinder. Gravity. This is my own rough sketch of a traditional gravity system. It's the same as an old coal fired system but with a gas boiler inserted in place of the original coal boiler in the kitchen.
suijitupian106.jpg" />However, with gas and oil firing, and modern quick and accurate response controls, this presents no difficulty and they are certainly as good, if not better, than similar conventionally designed field-erected boilers. A typical boiler supplied to the power station of a chemical works for power and space heating etc. is indicated in Figure 17
suijitupian16.jpg" />Feb 27, 2014 · Gas pressure switches are not installed on every boiler and are typically used when the gas rating of the burner is greater than 2.5 million Btu/hr. Safety shutoffs or valves are the next components in the gas train. Most likely it is two redundant electric valves that are to limit the chance of gas leaking into the boiler.

suijitupian109.jpg" />Conventional wisdom teaches that high total dissolved solids in boiler water increase tube corrosion and/or fouling. Indeed, that is true. High or highly fluctuating TDS will result in low heat transfer, reduced boiler capacity and efficiency, and shortened tube life. But it can also affect steam quality.
suijitupian40.jpg" />Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil
suijitupian157.jpg" />The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

suijitupian118.jpg" />In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called "Ultra-Low NOx" (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas.
