Embodiment Construction

[0023] The fully premixed gas-fired condensing vacuum hot water unit of the present invention includes a water inlet, a water outlet, an air inlet, a combustion chamber, a heat exchanger and a smoke exhaust port. The water outlet flows out; the gas enters from the air inlet, passes through the combustion nozzle, burns in the combustion chamber and transfers heat to the medium water in the vacuum body through the furnace, so that the medium water is vaporized to generate negative pressure steam, and the negative pressure steam flows in the heat exchanger tube The surface condenses, and the condensation process transfers heat to the cold water in the heat exchanger tube; the exhaust gas after combustion is discharged from the exhaust port. It also includes a gas-air mixing device, a control device, a flue gas condensing device, a temperature sensor, and a zirconia sensor, which are connected and fixed in the body.

[0024] The temperature sensor and the zirconia sensor are insta...

Abstract

The invention relates to the technology field of a gas hot-water machine, in particular to a fully premixed gas type condensate vacuum hot-water machine unit, the temperature and the oxygen content information of the waste gas are collected by a sensor and is input into a control device, the mixing ratio of the air and the gas is dynamically adjusted by the control device, thereby realizing the sufficient burning of the gas; by adopting a condensing device which heats medium water, the heat efficiency of the gas is increased, the structure of the machine unit is simplified and the volume of the machine unit is reduced. The invention provides a burner nozzle which is applied to a premixed gas type hot-water machine, the burner nozzle comprises a spraying rack pipe unit with a large pipe diameter and a damping rack pipe unit with a small pipe diameter, which are arranged side by side and can avoid flame lifting and the tempering.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, and specifically provides a fully premixed gas-fired condensing vacuum water heater unit, which realizes energy saving and environmental protection; and provides a combustion nozzle applied to a premixed gas-fired water heater, which can prevent deflagration Fire occurs. Background technique [0002] At present, more and more gas-fired boilers are used in the heating field of urban buildings in my country. Domestic gas-fired boilers mainly include steam boilers, atmospheric hot water boilers, and vacuum hot water units. Most of them use diffusion combustion technology. The main advantages are: stable flame, no backfire, and simple manufacturing of combustion equipment. But the disadvantages are incomplete combustion, excess air, relatively low thermal efficiency, and more pollutant emissions. [0003] Therefore, people research and explore the energy-saving technology of gas water hea...
