Since the latest advance of electronic devices and high-density and large-scale integrated circuits, the need for an enhanced heat transfer system is required (Rehman et al. 2013; 2009).Since such devices unavoidably releases a large amount of heat generation and they are in cramped space to equip a cooling system, there is a demand for appropriate cooling …
In the past researchers have tried methods to physically remove the salt by scraping it using mechanical scrapers driven using motor and pulleys, impinging a jet of freezing salt on tubes and letting the salt fall-off due to force from the jet, using a ball mill to break the salt from heat transfer surface and other mechanical means.

Convection heat transfer is the main form of heat transfer. The main factor determining the heat transfer strength depends on the thermal resistance in the boundary layer. The higher the air velocity is, the thinner the thermal boundary layer is, the smaller the thermal resistance is, and the stronger the heat exchange capacity is.
A boiler system includes a boiler having at least one heat exchanger having a surface on which a deposit may form. The boiler system further includes at least one retractable sootblower having a lance tube for carrying a high pressure fluid into the boiler. The lance tube is configured such that the high pressure fluid impacts the heat exchanger surface to effect a vibration in the boiler …
Vertical Kiln for Cement Plant. Among the many rotary kiln equipment, there is a type of kiln that is placed straight.This equipment is a vertical kiln. The working principle of this kiln is to continuously load large pieces of raw materials from the upper part, and the calcined raw materials are continuously Discharged below, the material moves from top to bottom due to gravity.
