Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.

Technical advantages

Digitized manufacture

  • The laying-off of steel tube adopts CNC 3D laser cutting machine.
  • The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
  • The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

Long life span

  • The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
  • Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.
  • Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

Less fuel consumption

  • Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50℃ to make the minimization of loss.
  • Furnace adopts double close line coil, which makes heating surface sufficient.

This type of blow down is common in high-pressure boilers. a large diameter line is opened for a short period of time. This flash steam can be used for pre-heating boiler feed water or for any other purpose. Also. Even though large quantities of heat are wasted. Blow down is necessary to protect the surfaces of the heat exchanger in the boiler.
