Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Referring to the structural representation that Fig. 1, Fig. 1 are gas heater first embodiments of the present invention.
The gas heater that the present embodiment provides, it includes burner 12, and is the burner 12 air inlet pipeline 13 for fuel gas, with the heat exchanger 10 of water inlet pipe 14 and outlet pipe 15, and discharges the smoke pipe 11 of waste gas for burner 12 and heat exchanger 10. Described burner 12 is for being heated heat exchanger 10, and heat exchanger 10 is for carrying out heat exchange process to the current flowed through in heat exchanger 10 pipeline, thus realizing current are heated. Gas heater is in long-term use procedure, owing to water containing calcium, magnesium plasma, the area that particularly hardness of water is bigger, calcium, the magnesium ion acid ion easily and in water when being heated is combined into the material of indissoluble, cohere and form incrustation scale on the inwall of gas heater pipeline, thus reducing the heat exchange efficiency of steam water heater and polluting bath water, the health of user is impacted. In order to remove the incrustation scale cohered in gas heater pipeline, the gas heater of the present embodiment also includes being arranged on water inlet pipe 14 ad-hoc location (such as, water inlet pipe 14 is positioned at the casing 16 position bottom casing 16, or, water inlet pipe 14 is positioned at the outer position bottom casing 16 of casing 16) apparatus for eliminating sludge 20, the preferred apparatus for eliminating sludge 20 of the present embodiment is arranged on water inlet pipe 14 and is positioned at the outer position bottom casing 16 of casing 16, thus apparatus for eliminating sludge 20 is operated by convenient user, such as, scale remover is added.
