Title: Flare Temperature and Nitrogen Oxide Emission Reduction and Heat Transfer in the TGMP-314I Steam Boiler Firebox

Abstract

Asolution is given to the problem of heat transfer in the firebox of a steam boiler, taking account of the radiation from all quadrillions of atoms constituting the flare. An innovative firebox for a steam boiler is proposed: the lower part of the firebox is a rectangular parallelepiped and the upper part a four-sided pyramid. The calculations show that in the proposed firebox the nonuniformity of the heat-flux distribution is diminished along the height and perimeter of the walls and nitrogen oxide emissions are reduced.

  • Test data have shown that reliable and efficient operation of boiler units of power stations can be maintained on low air excess with the controlled recirculation of flue gases. It is recommended that widespread adoption of this practice be made at power stations in order to decrease air pollution.
  • The 300 KW Kiev heat and power plant has a TGMP-314A straight-through supercritical pressure boiler which differs from other single-housing TGMP-314 boilers in that it has a steam separator installed on upper radiant heat section ahead of the rotation chamber screens. The performance of this boiler was evaluated. It was concluded that the TGMP-314A boilers have poor flexibility characteristics in comparison with other single-housing boiler units for 300 MW power units and this is caused by the change of the site of installation of the built-in separator unit in the boiler steam-water system; the steam enthalpy increment in the superheatermore » system of the TGMP-314A boiler unit during start-up is 1.5 to 1.7 times greater than in other types of boilers for 300 MW monounits; and in order to improve the flexibility characteristics of the TGMP-314A boiler the built-in separator unit should be installed after the rotation chamber screens, as calculated to provide a steam enthalpy increment in the steam superheater system of from 545 to 585 kJ/kg (130 to 140 kcal/kg).« less
  • This paper examines the combustion of the following gaseous fuels: 100% methane; methane with 20-60% hydrogen; methane with up to 80% heavier hydrocarbons (ethane, propane, butane, and pentane). The proposed method for calculation of the overall heat transfer in tube furnace fireboxes with a free flame according to the reduced characteristics of the fuel is explained as being based on a dimensionaless equatin for determinatin of the temperature of the gases at the exit from the firebox. The differences between the values of the gas temperature at the firebox exit is no greater than 10-15 K.
