Paper of the Year A Case Study on Coal to Natural Gas Fuel

Since natural gas has only trace amounts of ash, slagging and fouling would not occur. This lack of slagging and fouling may have a hidden risk of leading to more heat transfer problems in the boiler; coal-fired boilers are designed with a default assumption of a certain amount of slag and reflective ash coating their surfaces.

High Pressure Boiler - Industrial boiler and power plant

High Pressure Boiler is mostly water tube boiler in which water is on the tube side while flue gas flows through the tube, hence transferring heat from flue gas to water with cross flow heat transfer. A steam boiler is a high pressure boiler when it operates with the steam pressure above 6MPa. The high pressure boiler is widely used for power generation in thermal power plant.

How do heat exchangers work? - Explain that Stuff

Dec 08, 2018 · That's the design shown in our diagram up above. The two fluids can flow in the same direction (known as parallel flow), in opposite directions (counterflow or counter-current), or at right angles (cross flow). Boilers in steam locomotives work this way.

Fire-tube boiler - Wikipedia

Immersion fired boiler. The immersion fired boiler is a single-pass fire-tube boiler that was developed by Sellers Engineering in the 1940s. It has only firetubes, functioning as a furnace and combustion chamber also, with multiple burner nozzles injecting premixed air and natural gas under pressure.

Cross flow boiler -

an unfinned, cross-flow heat exchanger (boiler) with both fluids unmixed uses steam vaporizing in the tubes at 450K to cool down a high temperature gas that is in cross flow over the tubes. the gas, which has a specific heat of 1120j/kgK and a mass flow rate of 10kg/s, enters the heat exchanger at 1400K while the water (steam) has a flow rate
