ATMOSPHERIC BOILER - a boiler in which combustion air/flue gases are drawn through the boiler without a fan. Modulating atmospheric boilers are designed to control the output (size of flame) to match the boilers variable load requirements. During this process the burner is designed to stay at the correct fuel / air ratios across the complete firing range ensuring maximum combustion and boiler efficiencies. Modulation refers to a boiler's ability to match firing rate - input - to meet the heating demand - output - of the system. (https://tlj-eng.com/news/heating-boilers-what-you-need-to-know.html)
The boiler water level gauge is a detection instrument that shows the water level of the boiler, and it is one of the important safety accessories of the steam boiler.
At the same water temperature, the larger the excess amount of oxygen scavenger in water, the faster and more complete the chemical reaction. Under the same dosage, the higher the water temperature, the better the deoxidization effect. Under the same deoxidization effect, the higher the water temperature, the smaller the dosage.
When it is found that the boiler steam pressure can't rise, the first thing we should do is to check whether the water pump of the gas-fired steam boiler works and how much the pressure of the water pump of the gas-fired steam boiler can reach. When installing the water pump of the gas-fired steam boiler, a pressure gauge is installed on the water pump. This is because, if the gas-fired steam boiler does not add water, it can be detected whether it is caused by the water pump.
Industrial boiler is special equipment, the particularity and complexity determine that safety is its fundamental. In fact, the so-called safety door refers to the boiler explosion-proof door.
As a kind of special equipment, the safe operation of industrial boilers is the key point that every enterprise may pay attention to. Today, let’s talk about the normal water level in boiler operation.
During the normal operation, the steam drum water level maintains 0mm, and the allowable fluctuation range is ±30mm, with the maximum not exceeding ±50mm.
