High temperature and corrosion resistant electric heating plate
The temperature controlled electric heating plate, also known as the anti-corrosion electric heating plate, is a professional experimental electric heating plate for sample heating, digestion, drying, boiling and acid flushing. Its surface is treated with imported high-quality Teflon coating and is not affected by strong acids and alkalis.
Product features:
1. Imported Teflon anti-corrosion coating, which can be wiped clean and never rust, and anti-corrosion cast aluminum heating plate heats up quickly.
2. Multiple samples are processed at the same time without cross contamination.
3. All pillars of DBF type electric heating plate are made of polytetrafluoroethylene to minimize metal parts entering the laboratory.
4. Customized time setting function, segmented temperature control, and processing of different boards as required.
5. The panel and control box can be made into components, so that the acid mist during the experiment will not corrode the components in the control box, thus increasing the service life, and multiple samples can be processed at the same time without cross contamination.
DBF series anti-corrosion temperature control digital display electric heating plate is also called anti-corrosion electric heating plate and Teflon coated electric heating plate. The surface is treated with imported high-quality PFA anti-corrosion coating, which is a professional experimental hot plate for sample heating, digestion, drying, boiling, and acid flushing. A variety of series and models are available for users to choose from. They can also be customized according to users' requirements. They are made with special technology to overcome the disadvantages of ordinary electric heating plates that are easy to be damaged due to long-term continuous work. It can meet the needs of chemical laboratories in different industries such as physics, chemistry, biology, environmental protection, pharmacy, food, beverage, teaching, scientific research, etc. for reagent heating.

Every 20C heat recovered from Flue Gases translates to ~1% improvement in Boiler efficiency.
For flue gases with SOx and/or sooty, particulate material
Conventional heat exchangers suffer from cold spot and SOx condensation corrosion due to cold spots. Also, sooty flue gases offer challenges with respect to cleaning and maintenance in conventional exchangers.
HPHE operates at isothermal conditions and hence does not suffer from cold spot formation. Flue gases can be cooled close to the condensation temperature allowing higher heat recovery. Automated or manual in-situ cleaning of HPHE makes it an ideal exchanger for sooty flue gases.
This study focuses on a boiler producing 6 t/h saturated steam at 10 bars. Two fuel cases have been considered for this study, Briquettes and Natural Gas.
Briquette fired boiler
The flue gases will contain a high amount of particulate/soot. The evaporator section of the HPHE for this case has non finned smooth heat pipes and is fitted with an Ultra-Sonic soot blower.
The graph on the right shows the Cost Saved per year and HPHE CAPEX for 60, 80, 100, 120 �°C heat recovered from flue gases, assuming the flue gas exits the boiler at 200�°C.
Savings is calculated based cost of steam @ Rs 2.3/kg
Savings is calculated based cost of steam @ Rs 4.2/kg
Natural Gas fired boiler
The HPHE for this case will have fins in the evaporator section to improve the overall heat transfer. In case there is SOx in the flue gas, the gases can be cooled to a temperature close to the dew point at the stack exit.
The graph on the left shows the Cost Saved per year and HPHE CAPEX for 60, 80, 100, 120 �°C heat recovered from flue gases, assuming the flue gas exits the boiler at 200�°C.
The shown Savings and CAPEX figures are estimated values. Connect with us to find our the exact cost savings and HPHE CAPEX for your project.
