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.

Effects of Coal Rank on a Boiler Low Rank Coal Compared to Higher Rank Coal • Can have alkali elements directly attached to coal molecules rather than in the ash minerals such as clay, silica, alumina. • As a result the ash can have a high content of reactive sodium, potassium, calcium, iron and magnesium.

Pulverized coal-fired boiler - Wikiped

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.

THE I OPERATIONAL PARAMETERS ON BOILER ERFORMANCE A

The boiler system in consideration is a 500MW pulverized coal fired utility boiler. Schematic diagram of the boiler is shown in Figure 1. The boiler is of drum type with steam reheating. It has subcritical pressure of 170 kg/cm2 and forced circulation. It is fired with bituminous coal with tangentially corner fired combustion.

Generating Electricity from Coal - Duke Ener

In a coal-fired steam station – much like a nuclear station – water is turned into steam, which in turn drives turbine generators to produce electricity. Here’s how the process works. 1. Heat is created Before the coal is burned, it is pulverized to the fineness of talcum powder.
