摘要： PURPOSE: To make neutralization reaction sure and to prevent water leakage by providing plural staircase-like treatment tanks formed of a partition plate between both walls of a box body, disposing a cylindrical basic material in the bottom of each treatment tank and forming the box body and the partition plate into one body.
CONSTITUTION: The acidic dew condensate of 4.0pH and 30°C formed on the surface of a latent heat type exchanger is conducted at 120ml/h rate through an inflow port 4 into a body of the treatment device 1. The product of corrosion and dirt and removed in a settling tank 7, and the water drops through the guide groove 12 of a tongue part 11a into the cylinder of a neutralizer 10a. As a result, the acidic dew condensate flows from the bottom of the neutralizer 10a to the outside of the cylinder and is dropped through the guide groove 12 of the tongue part 11b provided on the partition plate 6b of a treatment tank 8a into the neutralizer 10b in the next stage until finally the water is discharged through an outflow port 5 to the outside of the body 1. The initial pH of the discharged acidic dew condensate is 7.3 and the pH after 3,000hr is 6.9. The neutral state is thus maintained.

CONSTITUTION:In order to provide 2 clearance between a treating tank 7 and a cylindrical basic material 8, the size of the tank 7 is made larger than the size of the material 8, and the material 8 is held afloat from the tank 7 by means of a projection 10 provided in the bottom part of the tank 7. Then, acidic condensate flows from the inside pipe part 9a of the material 8 to an outside part 8b. Further, a weir 11 is provided to the tank 7 and since the height of the weir 11 is made higher than the height in the bottom surface part of the material 8, the acidic condensate reacts by contacting with the material 8 and is thereby neutralized. The neutralized condensate flows out by overflowing from the weir 11.

摘要： PURPOSE:To impart energy-saving water supply, instantaneous water supply and hot water storing functions by forming a pump circulating path between a large capacity hot water storage tank and a heat source, disposing a heat exchange for the bath in the return path, and constituting the circulation path by three-way valves in a manner switchable to hot water supply faucet, tank lower part, tank middle part and bath heating. CONSTITUTION:Hot water in a large capacity hot water storage tank 1 circulated by a pump 12 through hot water supply reciprocating pipe 13, heat source 10, threeway switching electromagnetic valve 14, electromagnetic valve 27, hot water supply return pipe 15, orifice part 17 and three-way electromagnetic valve 16. In this case, when by switching the three-way switching electromagnetic valve 16 to communicate an inlet 5 for storing hot water in a large quantity, hot water stored in a large quantity can be obtained, and the three-way valve is communicated with the side of an inlet 6 for storing hot water in a small quantity, hot water stored in a small quantity can be obtained. Further, when the three-way vale 14 is switched to the side of the water supply faucet, the instantaneous hot water supply is started. When the electromagnetic valve 17 is closed in a state where a large quantity of hot water is heated up and hot water is flowed into the heat exchanger 27, additional heating of the bath can be performed. By this construction, a hot water supply bath unit combined with a low-input instantaneous hot water supplier and a large capacity hot water tank, which is energy-saving and convenient for use, can be obtained.

摘要： PURPOSE:To contrive reduction of pressure loss for secondary air supply, by a method wherein a high load combustor part is constituted by casting a heat exchanger pipe in aluminum material whose thermal conductivity is favorable and holding a flame hole, a secondary air jet and fin part for heat exchange between heat exchanger pipes. CONSTITUTION:As mixed gas reacts at a high temperature within a hatched area, a temperature of a flame hole 10 and a secondary air hole 11 becomes high, but if a device is a water boiler, the temperature can be reduced to a low temperature 50-100 deg.C as the temperature of the flame hole 10 and the secondary air hole 11 is close upon that of a material to be heated flowing within a heat exchanger pipe 9 as they are constituted of aluminum material having favorable thermal conductivity and the heat exchanger pipe 9 is built-in the vicinity of the flame hole 10 and the secondry air hole 11 in a body. With this, a fan can be miniaturized as the temperature is lowered and a pressure loss is reduced.

摘要： PURPOSE:To improve the heat exchange efficiency of the titled heat exchanger by a method wherein in the fuel combustion type heat exchanger for heating a liquid, a combustion gas is flowed horizontally and corrugated fins of predetermined height and pitch are attached to a pipe. CONSTITUTION:The corrugated fins 1 shaped to extend in the flow direction of the combustion gas designated by the arrow are attached tightly to the pipe 2 by expanding the pipe. In this case, the height (h) of the convex section of each of the corrugated fins 1 is determined to have a value between the pitch (p) and two times the pitch (p). With the above structure, the combustion gas flowing in the direction of the arrow runs against the corrugated fins 1 without fail and therefore, the water vapor in the combustion gas condenses to a saturation temperature same as the surface temperature of the corrugated fins 1. Further, corrosive condensed water is collected in the bottoms of the fins 1 to become separated from the combustion gas and accordingly, it is not introduced into the exhaust section, to thereby improve the heat exchange efficiency of the heat exchanger.

摘要： PURPOSE:To contrive the enlargement in high-load combustion and TDR (Turn Down Ratio) range in a combustion device for a heating system in which forced air supply is made through a fan, by a mechanism where in the combustion chamber walls are composed of fins and water tubes, with secondary air outlets being provided in stages in a part of the combustion chamber walls. CONSTITUTION:The amount of secondary air to be supplied via the No.1 and No.2 passages is properly adjusted through the adjustable dampers 6 and 7 respectively to be fed into the secondary air chambers 8 and 9. The secondary air then flows out of the secondary air outlets 10 and 11 to be directed uniformly at the flame forming in the combustion chamber 15. The secondary air jet stream sends the flame spreading all over the combustion chamber 15 so that the flame undergoes heat exchange at the heat exchanger 17 which is of one-piece construction with fin pipes to be let out of the exhaust port 18. In this way, the supply of secondary air enables large-capacity, high-load combustion, helping extend TDR control range. Besides, the combustion chamber walls designed to serve as heat exchanger help prevent rise in temperature of the secondary air chamber and keep secondary air from being heated excessively. This enables miniaturization of the burning system employing a small-size fan.
