Problems solved by technology

The defect of ZL96235429.5 is that the heat exchange is not sufficient enough to continuously supply high-temperature hot water for a long time
After testing, the temperature of the exhaust gas discharged after a heat exchange is often as high as 200°C, and direct discharge is a great waste of heat energy.
Moreover, because the heat exchange process is designed to be very short in this technology, the temperature of the released hot water is low, and it cannot be continuously supplied for a long time.
ZL96220136.7 has three-stage combustion and three heat exchanges, so it can supply hot water continuously for a long time, but it also has the problem of directly discharging the hot exhaust gas after combustion, so it makes full use of the oil in the oil and gas. Does not use the hot exhaust gas after combustion, causing waste of heat energy and low thermal efficiency

Embodiment 1

[0036] A continuous water supply hot water heater, which includes a heating furnace 1, a main water tank 5, an auxiliary water tank 12, an auxiliary water tank base 16 and an exhaust fan 18.

[0037] The heating furnace is mainly composed of a furnace body 32 and a waste heat utilization device, and the waste heat utilization device includes a water jacket 24 and a heating water pipe 23 . The water jacket 24 is in the shape of a tube with ears on both sides, and is arranged around the furnace body 32 . There are seven heating water pipes 23 arranged in two layers, three on the upper floor and four on the lower floor. The upper and lower layers of heating water pipes 23 are arranged in a staggered manner. All the heating water pipes 23 are connected in series, and the way of series connection can be the adjacent series connection of jumping floors, or can be series connection with another floor after being connected in series with the same floor. The two ends of every heating ...

Abstract

The invention provides a constant-water supply hot-water stove and relates to a boiler, in particular to a boiler capable of supplying hot water constantly. The boiler comprises a heating furnace and a primary water tank, wherein the primary water tank is arranged above the heating furnace and the heating furnace is provided with a waste heat utilization device. The boiler is characterized by also at least comprising a secondary water tank, a secondary water tank base and an exhaust fan, wherein the secondary water tank is arranged above the secondary water tank base, the primary water tank and the secondary water tank are provided with inverse 'U'-shaped exhaust pipes, the hearth of the heating furnace, the exhaust pipe of the primary water tank, the exhaust pipe of the secondary water tank, the secondary water tank base and an exhaust fan mechanism form a serial exhaust pipeline, and the secondary water tank, the primary water tank and the waste heat utilization device of the heating furnace form a serial water pipeline. The boiler has the advantages of dramatically improving the thermal efficiency of unit energy and constantly supplying high-temperature water for a long time.

Description

technical field [0001] The invention relates to a boiler, in particular to a boiler capable of continuously supplying hot water. Background technique [0002] We conducted a patent search on the keyword "continuous hot water supply", and the results involved 2 invention patents and 23 invention patents. Classifying the published patent documents, the above 25 technologies belong to water heaters, water dispensers, residential heating systems and boilers. The technology closest to the present invention has ZL96235429.5 and ZL96220136.7. The defect of ZL96235429.5 is that the heat exchange is not sufficient enough to continuously supply high-temperature hot water for a long time. This technology discharges the hot gas after combustion after only one heat exchange. After testing, the temperature of the exhaust gas discharged after a heat exchange is often as high as 200°C or more, and direct discharge is a great waste of heat energy. And because the heat exchange process is...
