Steam System Design

Saturated steam is a precision isothermal medium for process heating vessels employed in manufacturing operations, works utilities and site resources. It enables high rates of energy transference over long distances without need of mechanical intervention. Steam may be generated from any type of fuel, in any quantities, and within any chosen continuum of rate, temperature and pressure. It may be superheated beyond its natural saturation temperature to provide local high energy supplies for power, chemical and production operations. Steam system design is well-supported by a knowledgeable and ethical supplier basis, providing education, advice and off-site management services for site services and manufacturing applications.

Thermal Fluid Heating

We have designed and built several skid-mounted and integrated heating systems incorporating our shell-and-tube electric HTF heaters and thermal fluid calandria for synthetic fluid and hot oil recirculation. At temperatures above 340 degrees or so, vapour pressures of even the most tolerant synthetic fluids tend to rise above atmospheric. System design must ensure that operating conditions of thermal fluids do not affect their useful working life. Their replacement cost should be offset against the water treatment and attendance requirements of steam plant.

No thermodynamic pressure is induced during the heating of a thermal fluid if its vapour pressure remains below atmospheric, and engineering costs are much-reduced if systems are to operate only under gravity head. Generally speaking, electric calorifiers for thermal fluid and hot oil heating fall within SEP classification of the PED and are not CE marked. As they do not require ventilation for combustion air supply, electrically-fired and steam-heated calorifiers are suitable for installation in airconditioned spaces. Direct firing, resistance or induction heating may be used where liquid phase systems are impracticable.

Special Heat Exchangers and Heat Transfer Equipment

Most proprietary equipment comprises either plate type or shell-and-tube heat exchangers. While process installations or OEM plant & machinery might typically incorporate selections from standardized ranges of heat transfer equipment, gas turbines, road vehicles and mass-produced appliances generally employ special heat exchangers of compact, lightweight construction designed to meet host equipment configurations. Vessels might be heated by dimpled jackets, thermal fluid calandria or immersed coils. Precision machined castings, laser-cut profiles, low-volume pressings are likely to be mechanical prerequisites for custom applications, while the thermal process design of shell and tube heat exchangers calls for considerable knowledge and experience.

Heating Plant Designers

Dove Thermal designs, builds and commissions process heating vessels equipped with HTF calandria, jacketed or externally-recirculated batch heating vessels for heating and tempering duty in chemical and food production processes. We have designed and built various types of biothermal energy plant for biomass conditioning and space heating application.
