The bundle was installed in the outlet flue of a coal-fired test boiler to simulate flue gas and friable flyash conditions of a pulverized-coal-fired utility or industrial boiler. Thermal and hydraulic performance characteristics were measured to determine the effects of fouling and sootblower cleaning on bundle heat transfer and pressure drop.

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level.

15/2/2017 · The results show that the boiler efficiency improves by 3.2 percentage point when the exhaust temperature decreases to 39 °C. Also, the pressure drop in the heat exchanger remains below 400 Pa, which results in low extra electricity consumption. The direct-cooling treatment removes 59% of sulfur dioxide and 8.8% of nitrogen dioxide.

What to do if your boiler pressure is too low | Viessmann

If your pressure gauge is marked with a green zone and the needle has fallen below it, this is a sign that the gas boiler pressure is too low and action should be taken. If you have radiators that fail to heat up as they should, this may also be a sign that there is an issue with your boiler pressure and can be confirmed by checking the gauge.

To maintain high boiler efficiency, the carbon monoxide concentration in the flue gas must be kept below 15 to 20 ppm (wet basis). The last combustion efficiency loss is unburned carbon. This can be unburned carbon or partially burned carbon found in the ash pit or the flue gas (fly ash).
