nowl for maximum boiler efficiency

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.

How Boilers Keep the Plants and Refineries Running Smooth

The boiler should be designed to transfer the maximum amount of heat possible from the combustion into the water using processes such as radiation, conduction, and convection. The efficiency of the heat transfer is very important so that the fuel being burned yields the maximum, most cost effective results.

Fire-tube boiler - Wikiped

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction , heating the water and ultimately creating steam .

BOILERS | Energy-Models.c

The maximum efficiency of the boiler does not occur at full load, but at about two-thirds of the full load. If the load on the boiler decreases further, efficiency also tends to decrease. At zero output, the efficiency of the boiler is zero, and any fuel fired is used only to supply the losses.
