Water level regulator for vertical fuel oil and fuel gas boiler

Abstract

The invention relates to a water level regulator for a vertical fuel oil and fuel gas boiler. The water level regulator comprises a regulator body, wherein the regulator body comprises a U-shaped cambered surface iron plate, and a horseshoe-shaped side plate matched with the side surface of the U-shaped cambered surface iron plate is welded on the side surface of the U-shaped cambered surface iron plate; a safety hole is formed in the horseshoe-shaped side plate; a water feeding connecting hole matched with a water feeding pipe opening of the boiler is formed in the U-shaped cambered surface iron plate. A horseshoe-shaped water tank with an opening in one side is adopted, and the open side of the horseshoe-shaped water tank is welded on the drum inner wall of the boiler. Instead of being directly fed into the drum like before, water is firstly fed into the device and then flows into and permeates into the drum, and the water level stability of a water level gauge is ensured. The water level regulator is simple in structure and convenient to operate. The water feeding mode of the boiler drum is improved and accidental boiler stop and losses cannot be caused by water feeding.

Description

【Technical field】 [0001] The invention relates to a vertical fuel oil and gas boiler water level regulator device. 【Background technique】 [0002] Vertical oil-fired gas boiler, the water capacity of the drum is small, the temperature rises quickly, the fire is fierce, and the alkalinity is indeed less controllable than the coal-fired chain grate furnace steam boiler. If you are not careful, when the water is automatically supplied, it will be due to the low water level chain protection device action, resulting in instantaneous and unexpected shutdown of the furnace, resulting in losses; and because its alkalinity is not easy to control, it is easy to cause unstable combustion status of the boiler; therefore, the corresponding method on the market is: through the boiler combustion controller computer, the alkalinity of the boiler water is controlled The index is also written into the program, which is convenient for automatic control, but its range cannot exceed the range of...
