Kraft EnergyTM Vapor Curing Systems
The direct-fired vapor generator is designed for accelerated curing of Precast concrete products.
Precast concrete applications include cast stone, block, paver, flag/slab and curb, manhole and roof tile products.
The direct-fired vapor generator provides the benefits of accelerated concrete curing, such as:
- moisture and heat
- shorter hardening time
- 30% less racks and pallets
- in-line secondary processing
- immediate shipping
|
- less breakage
- quicker packaging
- more complete hydration
- reduced cement
- uniformity in strength and colour
|

Principle Behind Vapor Curing Systems
Pre-mixed air (A) and gas (B) are ignited in the water cooled mixer-burner (C) mounted on top of the stainless
steel combustion chamber (D). A precisely metered quantity of water enters the outer jacket (E) of the double-walled,
stainless steel combustion chamber.
The water flows up the outer jacker across the annulus (F) and down the inner wall (G). As the water moves down
the inner wall, towards the vapor outlet (H), it is heated, through direct contact, by the extremely hot combustion
gases. As the mixture exits the combustion chamber, it passes through the static mixer (I) to insure homogeneous mixing.
