Main technical advantages of our low temperature economizer
1. The equipment body can be designed into many modules to ensure
the long term and stable running;
2. The low temperature economizer manufactured by our company can
guarantee the wall temperature is 5-10 ℃ higher than the acid , and
flue outlet temperature is 10-15 ℃ higher than the wall surface
temperature
3. Wall surface temperature can be adjusted according to the boiler
load and fuel changer to avoid corrosion under low temperature
4. Changer the DCS system of the existing boiler to achieve the
auto and remote control by computer.
