Vertical boiler

Abstract

The invention discloses a vertical boiler which comprises a boiler body, a smoke circulating system arranged in a boiler cavity, a water storage chamber, a water inlet pipe and a water outlet pipe which are arranged on the boiler body, wherein the boiler body is divided into an upper boiler body and a lower boiler body which are independent to form an upper water storage chamber and a lower water storage chamber, the smoke circulating system comprises a combustion chamber arranged in the boiler cavity, a plurality of smoke chambers, a heating smoke discharging pipe and a towering pipe, the heating smoke discharging pipe and the towering pipe are connected with the smoke chambers, the cross section of the heating smoke discharging pipe is arc-shaped, and the boiler is externally provided with a water circulating pipeline for connecting the upper water storage chamber with the lower water storage chamber. By using the vertical boiler provided by the invention, the smoke is purified by using the smoke circulating system in the boiler, thus the content of impurities in the smoke discharged in atmosphere is reduced, the heating area of the heating smoke discharging pipe is enlarged, and the water is fully circulated and heated by combining with the water circulating system, and the heat utilization rate of smoke is increased. The vertical boiler has the advantages of simple structure, convenience for use, energy saving and environment friendliness.

Description

technical field [0001] The invention relates to an atmospheric pressure hot water boiler, in particular to a vertical boiler. Background technique [0002] At present, the normal-pressure hot water boiler used in daily life is an integral structure, which is mainly composed of a furnace shell, a furnace, a cupola, a horizontal water pipe and a combustion chamber built in the furnace. The circulating water of this boiler is automatically From bottom to top, it circulates through the water storage chamber formed between the furnace shell and the furnace and the horizontal water pipe connected to the water storage chamber. The furnace is separated between the water storage chamber and the combustion chamber, and the temperature rises slowly. The gas flows upward in the furnace to heat the horizontal water pipe, and directly enters the external chimney through the cupola to be discharged into the atmosphere. The heat energy utilization rate of the discharged flue gas is low, and...

[0002] At present, the normal-pressure hot water boiler used in daily life is an integral structure, which is mainly composed of a furnace shell, a furnace, a cupola, a horizontal water pipe and a combustion chamber built in the furnace. The circulating water of this boiler is automatically From bottom to top, it circulates through the water storage chamber formed between the furnace shell and the furnace and the horizontal water pipe connected to the water storage chamber. The furnace is separated between the water storage chamber and the combustion chamber, and the temperature rises slowly. The gas flows upward in the furnace to heat the horizontal water pipe, and directly enters the external chimney through the cupola to be discharged into the atmosphere. The heat energy utilization rate of the discharged flue gas is low, and the discharged flue gas contains a large amount of waste gas, which pollutes the environment
