The links between Waddington’s can be traced back over 30 years.
As the JBC organisation grew, the first major contract between the
two companies was the conversion of their twin flue Robey coal fired
boiler to natural gas.
The boiler was rated at 9’000kg/h and fitted with fixed grates
and grit arrestors etc. Twin Hamworthy AWG gas burners and control
panel were installed along with the necessary gas supply and booster
unit.
An important feature was the burning of foul air from the cooking
process. An earlier method of burning the foul air was to pull the
air through the FD fan inlet but this led to coating of the burner
and fan impellor with tallow (animal by-product) and was not practical.
Working in conjunction with Hamworthy Combustion Ltd a new improved
system was designed which injected the foul air from a point within
the furnace thus eliminating the occurrence of tallow to the FD fan
and burner.
In 1996/7 it was decided that a new factory was required. JBC was
awarded the contract to supply the steam services including steam
distribution pipework systems within the production area.
In a £500k turnkey project two 9’000kg/h steam boilers
were supplied and installed together with flue, hotwell, gas supply
and blowdown facilities etc. This was a large contract, which once
again featured the improved foul air incineration design but this
time using Saacke burners.
These burners were specified as they are capable of burning ordinary
fuel oils and tallow, which is acidic and abrasive.
As new legislation's were introduced in 2003, it was necessary for
Waddingtons to have a thermal oxidiser installed. This system puts
foul air from many parts of the process which is then injected into
incinerators. The hot gases pass through a 13’000kg/h waste
heat boiler consequently raising steam for the process and incinerating
smells simultaneously.
JBC designed and installed all the steam and gas services as well
as stainless steel ductwork within the process area in a contract
worth £250k. |
