An atmospheric hot water boiler

Abstract

The utility model relates to an atmospheric pressure hot water boiler, which is mainly composed of a boiler body consisting of a boiler upper body, a lower body, and a heat exchanger detachably connected. The water circulation channel of the heat exchanger is connected with the water circulation channel of the upper and lower body of the boiler, and communicated with the water supply source through the electric control valve to form a boiler water circulation circuit. The flue gas circulation passage of the heat exchanger communicates with the flue gas circulation passages of the upper and lower bodies of the boiler through the chimney, and communicates with the dust removal pool to form a boiler flue gas circulation loop. The automatic control device is electrically connected with the furnace top water temperature probe, the boiler outlet hot water temperature probe, the preheated water temperature probe on the heat exchanger, the induced draft fan and the electric control valve. Automatic safety exhaust valves are installed on the upper and lower bodies of the boiler and the heat exchanger respectively. The boiler can fully utilize heat energy, improve thermal efficiency, and has low exhaust gas temperature, fast water outlet speed, high and stable water temperature, and large flow rate. It can also effectively save energy, reduce emissions, reduce consumption, and has a good environmental protection effect.

Description

technical field [0001] The invention relates to a boiler, especially an atmospheric hot water boiler, which is suitable for heating and bathing. Background technique [0002] At present, people once used a kind of normal pressure hot water boiler when heating and bathing. , The lower three layers of horizontal water pipes, the chimney located above the pot shell is connected with the furnace gall through the cupola. The circulating water in this boiler circulates from bottom to top through the water storage chamber formed between the pot shell and the furnace and the horizontal water pipe connected to the water storage chamber. Its heating area is small, the water capacity is large, and the coal consumption is low. Many, slow heating. However, the burning flame in the combustion chamber directly radiates the furnace.

Problems solved by technology

The circulating water in this boiler circulates from bottom to top through the water storage chamber formed between the pot shell and the furnace and the horizontal water pipe connected to the water storage chamber. Its heating area is small, the water capacity is large, and the coal consumption is low. Many, slow heating

However, the burning flame in the combustion chamber directly radiates the furnace. After the high-temperature flue gas flows upwards to heat the horizontal water pipe, it enters the chimney directly through the cupola and is discharged. The flue gas flow is short and the combustion is insufficient. A large part of the heat is discharged with the flue gas. lower, while the exhausted flue gas temperature is higher, resulting in energy waste

Moreover, when the water temperature is too high, scale will easily form in the horizontal water pipe, which will easily cause the water pipe to burst, shorten the service life of the boiler, and bring trouble and loss to the user.

At the same time, this kind of boiler is also inconvenient to maintain
