Ignition control method and device for gas wall-hung boiler and gas wall-hung boiler

Abstract

The invention discloses an ignition control method and device of a gas wall hanging stove and the gas wall hanging stove. The method comprises the steps of: enabling the ignition control on the gas wall hanging stove to perform primary ignition on the gas wall hanging stove; determining if the primary ignition is successful; and increasing the ignition power of previous ignition according to a preset amplification and / or preset acceleration when the primary ignition is failed, and performing secondary ignition according to the increased ignition power to satisfy the safety ignition demands of the gas wall hanging stove to the greatest extent in a preset safety ignition power interval. The method can overcome such defects as low ignition success rate, influence on the service life and weak user experience in the prior art, and realizes the beneficial effects of high ignition success rate, no influence on the service life and good user experience.

Description

technical field [0001] The invention belongs to the technical field of gas wall-hung boilers, and in particular relates to an ignition control method and device of a gas wall-hung boiler and a gas wall-hung boiler. Background technique [0002] Gas wall-hung boilers (that is, gas wall-mounted heating furnaces) can burn gas, exchange heat with circulating water in the main heat exchanger through high-temperature flue gas, and continuously take out the heat under the drive of the circulating pump, and finally Enter the radiator to increase the temperature of the room, or enter the plate exchange (for example: plate heat exchanger) to exchange heat with tap water to realize domestic hot water supply. [0003] During the daily use of a gas wall-hung boiler, whether it is heating or providing domestic hot water within a short period of 24 hours, it will go through start-stop-restart, repeated many times, not to mention that the use standard of a wall-hung boiler is 20 years .
