Problems solved by technology

[0002] Traditional gas-fired wall-hung boilers are usually equipped with corresponding devices such as combustion chambers and heat exchangers. Because the flue gas takes away a considerable part of the energy, the thermal efficiency is limited and the heat utilization rate is difficult to improve. A set of flue gas secondary condensation system is added on the top. The combustion chamber heats the main heat exchanger by burning gas to generate high-temperature flue gas, which is drawn into the flue gas chamber by the fan, and cold water enters the secondary condensation heat exchanger from the water inlet pipe to absorb the combustion chamber. The generated high-temperature flue gas heat preheats the hot water flow, and at the same time cools the flue gas, and precipitates condensed water and inorganic salts. However, due to the large water resistance, the flow rate will be small

Abstract

The invention discloses a capping type heater for a water container. The capping type heater comprises a heat exchanging tube assembly, flue gas flow guiding plates, a smoke separating plate and the water container; the water container is provided with a water inlet and a water outlet, and the two ends of each heat exchanging U-shaped copper tube in the heat exchanging tube assembly communicate with the water container; the water inlet communicates with one ends of all the heat exchanging U-shaped copper tubes, and the water outlet communicates with the other ends of all the heat exchanging U-shaped copper tubes; the flue gas flow guiding plates are arranged on the two sides of the heat exchanging tube assembly, and the smoke separating plate is arranged in the middle of the heat exchanging tube assembly; a sealing cover is further arranged on the water container, and screwed joints are correspondingly arranged at the water inlet and the water outlet of the water container; through holes which correspond to the water inlet and the water outlet are formed in the sealing cover, the water container is covered with the sealing cover, and the sealing cover and the water container are fixedly connected through screws; and the screwed joints upwards penetrate through the corresponding through holes in the sealing cover and are fixed through hexagon nuts. The capping type heater for the water container has the characteristics of reasonable structure, convenient production and low production cost.
