摘要： PURPOSE:To prevent generation of unvaporized aqueous ammonia in an evaporator and blow-up of aqueous ammonia droplets by atomizing in the specified rate of atomized medium to the amount of aqueous ammonia through a nozzle device for two fluids into the evaporator, and supplying the generated gaseous ammonia to a denitration equipment by gas for dilution at a prescribed temp. CONSTITUTION:Aqueous ammonia 1 is atomized together with a medium 2 for atomization through a nozzle device 3 for two fluids into an evaporator 4. Further, the rate of the amount of atomized medium to the amount of aqueous ammonia is regulated to 250-600. Air 6 for dilution is pressurized by a fan 5 and then heated by a heater 7 provided in the evaporator 4. This air 6 for dilution is mixed with the atomized droplets 8 of aqueous ammonia 1 which is sprayed through the nozzle 3 and atomized. The atomized droplets 8 are completely evaporized while this mixture flows through the evaporator 4 and become a gaseous mixture 9. This gaseous mixture 9 is introduced into a denitration equipment 21. In such a way, it can be prevented that the atomized droplets of aqueous ammonia may become drain in an ammonia evaporator, or may pass through the evaporator while being not vaporized.

摘要： PURPOSE:To evaporate all the aq. ammonia supplied and to surely conduct the vapor on a denitration catalyst by setting the evaporator outlet temp. at a value obtained by adding the temp. drop corresponding to the load change in the necessary evaporation amt. and temp. drop due to the heat loss on the downstream side to the dew point of the outlet gas. CONSTITUTION:Aq. ammonia 1 is directly sprayed into the air heated by an air heater 6 to obtain the air-diluted gaseous ammonia. In this case, the downstream temp. after the evaporation completion point in an evaporator 11 is set at the value obtained by adding the temp. drop due to the heat loss from a downstream pipeline 15 and temp. drop due to the difference between the heating rate of the air heater 6 and the increasing rate of the necessary evaporation amt. of aq. ammonia to the dew point of the gaseous mixture after evaporation. Consequently, all the ammonia supplied is evaporated, the gaseous ammonia is surely conducted on a denitration catalyst without condensing it in the downstream pipeline, and stabilized and efficient waste gas denitration performance is obtained.

摘要： PURPOSE:To make it possible to recognize visually a heat pipe, which has gotten into performance degradation, and exchange the heat pipe by applying or adding materials such as a thermo-paint, which are discolored according to temperature change, on the outside face of the condensation part of the heat pipe. CONSTITUTION:In the thermal exchange which transfers the heat of a high-temperature fluid to a low-temperature fluid, plural heat pipes 2 having fin 3 are inserted to tube plate 8 which divides casing 1 into two ducts, and therefore, the heat of high-temperature fluid 6 is transferred to the low-temperature fluid 5 side through heat pipe 2. The edge of heat pipe 2 in the low-temperature fluid 5 side is a condensation part and is protruded from wall face 4 of casing 1 to the external, and thermo-paint 7 is applied around the condensation part. Since a heat pipe where non-condensed gas 10 is generated inside due to the change in elapse has the temperature in the condensation part lowered in comparison with a normal pipe, the heat pipe which has gotten into performance degradation can be found by confirming the color change of thermo-paint 7 on the condensation part.

摘要： PURPOSE:To prevent the heat transmitting efficiency from lowering, by fitting a filter for permeating non-condensive gas to an end of a hemertic container and exhausting the non-condensive gas generated inside the container. CONSTITUTION:A filter 6 is fitted to a flange 8 at an end B of a hermetic container 1. Since most part of non-condensive gas generated in the container 1 is hydrogen gas, the filter 6 is preferably made of porous glass which allows only hydrogen gas to pass through. The filter 6 is fixed to the container 1 together with the flange 8 by means of a fitting flange 9. When heat 5 is given to an end A, the working fluid 4 is evaporated to discharge its latent heat at the cooling end B and then is recirculated to the heating section. Since the non-condensive gas 7 including hydrogen gas generated during this process is exhasuted through the filter 6 outside the container 1, the efficiency of heat transmission is not lowered.
