| 182 | FEEDWATER HEATER | EP03703743.9 | 2003-01-09 | EP1468222A1 | 2004-10-20 | RECHTMAN, Yuri, M. |
| A feedwater heater for a steam generator (A) or heat recovery boiler or waste heat boiler through which hot gases pass includes two sections (26, 28) which are located side by side so that the temperature of the hot gases at the upstream face (30) of each section is essentially the same. The feedwater flows through a heat exchanger (34) before entering the first section, and here it is heated by water flowing from the upstream face of the first section to the downstream face (32) of the second section. The arrangement is such that all tubes in the two sections remain above the dew point of the hot gases, so that water does not condense on the tubes and unite with oxides of sulfur to form sulfuric acid which will corrode the tubes, yet substantial temperature differentials exist between the water in the sections and the hot gases as the gases pass through the sections. | ||||||

| A process and device are disclosed for utilizing the energy of flue gasses from coal-fired power stations in which the flue gasses are cleaned in a flue gas scrubber and guided into a cooling tower. The object of the invention is to allow energy content of flue gasses from coal-fired power stations to be ingeniously used even after the flue gasses have been washed in the washing tower, and thus also to use their wet fractions. For that purpose, the desulphurized flue gasses are cooled down to the water dew point in a mist collector known per se, before the flue gas outlet, and the perceptible latent heat thus withdrawn is used for preheating the machine condensate immediately after the machine condenser. The extraction steam known in the state-of-the-art is used in a first low pressure preheating stage to generate additional electric power and thus to increase the power generated by the power station. | ||||||

The invention relates to a method for the utilisation of the residual heat of flue gases having a temperature, which exceeds their dew point and containing aggressive constituents, in particular of flue gases discharged from solid fuel fired boilers. The flue gases are blown along the process water causing the thermal energy of the flue gases to be transferred to the process water in order to heat the latter at most up to the boiling temperature of the same under given ambient atmospheric and pressure conditions, the pH value of the process water being adjusted to enable the neutralization of the corrosive action of the condensing flue gas constituents. After the process water is heated up by the flue gases, its heat is transferred to the cooling water. Then, the cooled process water re-enters the flue gas flow in order to extract thermal energy from it. The device for performing the method according to the invention comprises the direct-contact heat exchanger (1) for extracting heat from the flue gases and transferring it to the process water, the direct-contact heat exchanger (1) having a flue-gas inlet, which is connected to the flue-gas outlet of a solid fuel fired boiler and/or to that of an incineration plant producing flue gases that contain aggressive constituents, said flue gases being led through the direct-contact heat exchanger (1). On the opposite end of the direct-contact heat exchanger (1), the water inlet is arranged for contact heat transfer between the flue gases and the process water. The process-water outlet of the direct-contact heat exchanger (1) is connected to the process-water inlet of the second heat exchanger (6) for extracting heat from the process water and transferring it to the cooling water, while the process-water outlet of the second heat exchanger (6) is connected to the process-water inlet of the direct-contact heat exchanger (1). The process-water circuit comprises the inlet for connecting the apparatus (5) for replenishing alkali into the process water in order to maintain the pH value of the process water at a level enabling the corrosive effect of the acids, which are produced during the condensation of flue gases, to be neutralized.

A coal-fired power plant having a control unit including a first flow rate control valve for regulating a water flow rate of a water feed bypass system, a second flow rate control valve installed in an extraction pipe for extracting steam from a steam turbine, a first temperature sensor on a downstream side of a heat recovery device, and a second temperature sensor on a downstream side of a heat exchanger and the control unit regulates opening of the first and second flow rate control valves on the basis of an exhaust gas temperature detected by the first temperature sensor and a feed water temperature detected by the second temperature sensor. Accordingly, even when a recovery heat quantity of the heat recovery device installed on a gas duct is changed due to deterioration with age of a boiler, a reduction in plant reliability and plant efficiency can be suppressed. |
