Embodiment Construction

[0037] Examples such as Figure 1-9 As shown, a preheating combustion coil condensing heat exchanger includes a detachable main body, and the detachable main body is sequentially provided with a pretreatment device for preheating and mixing the gas to be combusted by using the waste heat of the equipment itself according to the flow direction of the gas, A burner 2 for gas combustion and a heat collector for energy absorption by the medium (water).

[0038] The detachable body includes an upper cover 12 arranged above the burner 2 , and the pretreatment device is located between the burner 2 and the upper cover 12 .

[0039] The upper cover 12 is provided with an air intake cavity 4 for easy gas entry, the lower end of the upper cover 12 is encapsulated by a ring-shaped sealed upper cover 3 , and the burner 2 is mounted on the sealed upper cover 3 .

[0040] The heat collecting device is arranged under the sealed upper cover 3, and the heat collecting device is a coil 14, and...

Abstract

A preheating type combustion coil condensation heat exchanger comprises a detachable main body, and a pretreatment device for preheating and mixing the to-be-combusted gas through the own waste heat,a combustor facilitating gas combustion and a heat collecting device facilitating the energy absorption of a media are sequentially arranged on the detachable main body along the gas flowing direction. According to the present invention, various performance indexes of the heat exchanger meet the standard of GB25034-2010 gas heating water heater, the problem of condensate water corrosion can be effectively solved, the emission amount of the nitric oxide (lower than 30 mg / M3) and the CO is lower than 300 ppm, a coil pipe can be detached to be cleaned or replaced, the after-sales maintenance is facilitated, and the temperature of the combustion cavity is effectively reduced.

Description

technical field [0001] The invention relates to a fully premixed heat exchanger for a wall-hung boiler, in particular to a preheating type combustion coil condensation heat exchanger, belonging to the technical field of fully premixed condensation heat exchange. Background technique [0002] In the field of gas boiler applications, including gas heating water heaters and commercial gas boilers, driven by national environmental protection policies, the energy efficiency level of boilers is increasingly required to reach the first-level energy efficiency (see GB20665-2015 "Household Gas Instant Water Heater and Gas Heating Energy Efficiency Limits and Energy Efficiency Grades of Water Heaters"), flue gas emissions, especially CO (average hourly concentration limit value less than 2000ppm) and NOX (average hourly concentration limit value less than 30mg / M3) also have strict requirements (see GB25034-2012 "Gas Heating Water Heater", GB13271-2014 "Emission Standard of Air Polluta...
