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℃.

Effects of Air Staging Conditions on the Combustion an

A three-dimensional numerical investigation is presented on the coal combustion and NO x emission in a supercritical 600 MW wall fired utility boiler fed with lean coal. The distributions of velocity, temperature, and species were obtained using a finite volume method and some validated submodels.

Aerodynamic characteristics of a 350-MWe supercritica

In total, 16 burners were evenly and symmetrically situated at the arches, with each burner corresponding to one cyclone separator dividing the primary coal/air mixture into fuel-rich and fuel-lean flows for the regulation of fuel rich/lean combustion.

CN1687641A - Cold static ignition under meagre coal an

According to a lean coal oil micro and ultra cold ignition load stable combustion burner according to claim 1, characterized in that, (3) the amount of the pulverized coal into the combustion chamber of a pulverized coal is coal 30-40% by weight of the total powder.

Numerical Simulation of Gas-Solid Two-phase Flow in Horizontal Rich/Lean Pulverized Coal Burne

In order to ensure stable combustion at low-load, reduction of NOx emission, avoid slagging and high temperature corrosion in the combustion chamber, as well as to improve boiler combustion efficiency, many pulverized-coal boilers in large power plants have adopted the horizontal rich/lean pulverized-coal combustion technology.

,pulverized coal rich/lean burner,

The present model (RNG ASM) was applied to simulate the swirling jet flow from a pulverized coal rich/lean burner.

Experimental Study on Boiler Performance and NOx Emissio

burner type and coal type on NOx emission and boiler efficiency. The test data shows that the performance and NOx emission of the boilers are considerably impacted by boiler configuration, burner type and coal

Development of Ultra-low NOx Coal-firing Burn

However, our PM burner has a pair of two coal burner nozzles, feeding pulverized coal separately according to its concentration in the air (rich and lean) to form a coal rich flame and a coal lean flame, respectively.
