The most powerful commercial condensing boiler in the world, the E-Compact Twist is available in a wide range of outputs of 25kW up to 150kW, and is ideal for business owners who are looking to run a more energy-efficient business. The only condensing pellet boiler in the world with a single heat exchanger, the E-Compact Twist condensing boiler can achieve efficiencies of up to 103%.
This is basically A heat transfer equipment to heat air prior to entering in the furnace with a primary object to increase thermal efficiency of hot flue gases are passed through the tubes and air outside the tubes. The heat of the boiler flue gas is recovered in APH to increase the air temperature & the thermal efficiency is increased. Another advantage is that the flue gas is sent to chimney stack at lower temperature allowing simplified design of ducting & flue gas stack. It also allow controls the temperature of flue gas leaving the stack to meet emissions regulation / pollution control.
Salient Features:
Easy installation
Low maintenance cost
Robust construction
Compact
High efficiency
The rotating-plate design (RAPH) consists of a central rotating-plate element installed within a casing that is divided into two (bi-sector type), three (tri-sector type) or four (quad-sector type) sectors containing seals around the element. The seals allow the element to rotate through all the sectors, but keep gas leakage between sectors to a minimum while providing separate gas air and flue gas paths through each sector.
Tri-sector types are the most common in modern power generation facilities. In the tri-sector design, the largest sector (usually spanning about half the cross-section of the casing) is connected to the boiler hot gas outlet. The hot exhaust gas flows over the central element, transferring some of its heat to the element, and is then ducted away for further treatment in dust collectors and other equipment before being expelled from the flue gas stack.
The second, smaller sector, is fed with ambient air by a fan, which passes over the heated element as it rotates into the sector, and is heated before being carried to the boiler furnace for combustion.
The third sector is the smallest one and it heats air which is routed into the pulverizers and used to carry the coal-air mixture to coal boiler burners. Thus, the total air heated in the RAPH provides: heating air to remove the moisture from the pulverised coal dust, carrier air for transporting the pulverised coal to the boiler burners and the primary air for combustion.
