Because it does not store water like a traditional shell-and-tube storage calorifier
, which must store water at 60[degrees]C or higher to aid the prevention of Legionella growth, less energy is needed to heat the water.
"What we have is a microprocessor control on the calorifier
itself, which gives a signal on requirement, so it doesn't switch on the boiler unless there's a requirement.
The whole plant simulation model was developed using TRNSYS (SEL 2000), which adopted the Davidon-Fletcher-Powell algorithm (Powell 1964) for solving a set of nonlinear equations from the simulation components, especially the thermal solar collector and hot-water calorifier
. The flat plate collector was selected and installed at one single orientation of the building.
Lister Marine's Alpha diesel engines are equipped with standard features including a Hurth reversing gearbox with 2:1 reduction, 12 V starter motor, 55 amp marine alternator, heat exchanger, water-cooled exhaust manifold, raw and fresh water pumps, calorifier
connections, fuel filter with water trap, self-bleed fuel system, fuel lift pump, individual fuel injection pump for each cylinder, high level oil filler, and dipstick and sump drain pump.
In boiler flue, lagging on pipework, calorifier
If storing water at 60 [degrees] C is not practical or acceptable or the calorifier
is not in use for 1 week or more, raising the temperature of the calorifier
water to 70 [degrees] C to 75 [degrees] C for 1 hour will kill legionellae.
Tangerine Confectionery have all the confectionery produced at the company's confectionery processing plant at Clifton Road, Blackpool, cooked using steam, which is generated by a modulating steam boiler via a calorifier
. The steam is distributed via a 2 72 inch ring main to the various processing lines.
"Our old calorifier
system used to give us lots of problems," says Bendick's engineer Keith Wallace.
