Multistage condensation miniature hot water stove

Abstract

The invention discloses a multistage condensation miniature hot water stove, comprising a stove body and a combustor. A heating tank is mounted in the upper portion of the stove body; a heating grateis mounted in the combustor; the inside of the stove body is divided by two horizontal partitions which are circular into a primary waste heat exchange area, a secondary waste heat exchange area and atertiary waste heat exchange area sequentially from top to bottom; a plurality of high-temperature tail gas inlets communicated with the combustor are arranged evenly in the primary waste heat exchange area in spaced manner; an intensive exhaust fan is externally connected to the tertiary waste heat exchange area and is connected with a tail gas discharge pipe; a water incoming pipe is also connected with the tertiary waste heat exchange area; a hot water outgoing pipe is connected to the top of one side of the primary waste heat exchange area; a water outlet of the hot water outgoing pipe ispositioned in the heating tank. The multistage condensation miniature hot water stove has the advantages that high-temperature tail gas generated by the combustor is subjected to efficient heat exchanging, hot water produced by heat exchanging is delivered into the heating tank, energy consumption for heating is reduced, and application cost is reduced.

Description

technical field [0001] The invention belongs to the field of gas stoves, and in particular relates to a multi-stage condensing miniature hot water stove. Background technique [0002] At present, gas-fired boilers are generally used in the market to produce hot water, which occupy a large area, require a large investment, and are inconvenient to manage. When the boiler produces hot water, its high-temperature exhaust gas takes away part of the heat, resulting in a decrease in the thermal efficiency of the boiler, and it is not very suitable for small collectives and small groups to use boilers for hot water production, which increases the investment cost and management production cost of the enterprise . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage condensing miniature hot water stove, which can effectively improve thermal efficiency and reduce investment, management and production costs compare...

[0002] At present, gas-fired boilers are commonly used in the market to produce hot water, which occupy a large area, require large investment, and are inconvenient to manage.

When the boiler produces hot water, its high-temperature exhaust gas takes away part of the heat, resulting in a decrease in the thermal efficiency of the boiler, and it is not very suitable for small collectives and small groups to use boilers for hot water production, which increases the investment cost and management production cost of the enterprise
