2 · SuperCritical flow. The flow at which depth of the channel is less than critical depth, velocity of flow is greater than critical velocity and slope of the channel is also greater than the critical slope is known as supercritical flow. The channel is called as shallow channel for supercritical flow.

Get a QuoteThe Difference Between Steam & Hot Water Boilers. Businesses, in all kind of industries, use boilers to meet the energy demands of their facilities. Those needs may vary. There are two types of boilers to choose from — hot water or steam boilers. The key difference between the two comes down to
Get a QuoteSupercritical boiler that is usually applied to 400 MW systems or larger; the design features a water-cooled dry-bottom furnace, superheater, reheater, economizer, and air heater components. Designed for both base load and full boiler variable pressure load cycling operation as well as on/off cycling operation.
Get a QuoteThe difference between subcritical and ultra-supercritical technology is that the total amount of flue gas emitted from the ultra-supercritical plant is about 14 per cent smaller, and hence the capacity of the SO2 control device can be about 14 per cent lower, resulting in savings in investment and operating costs.
