Energy-saving water boiler

Abstract

The invention relates to an energy-saving water boiler which is characterized by overcoming the defect that a chimney is directly arranged on a hearth or behind the hearth of a stove of a boiler in the prior art, enabling a fire tail to make a turn and retaining high-temperature gas in the boiler, thereby enhancing the heat efficiency. The energy-saving water boiler comprises a boiler body (7), a combustion chamber (8) and a boiler door (13). The energy-saving water boiler is characterized in that the upper part of the inner circumference of the boiler body (7) is closed; the upper part of the combustion chamber (8) is integrally provided with a movable or fixed fire guider (4); and the connecting part of the port of the fire guider and the combustion chamber is provided with a male-female groove (12). The invention has the advantages that the fire guider (4) enables fire to enter the closed upper part of the boiler body (7) according to certain differential pressure, the high-temperature gas is retained at the upper part of the boiler body (7), and tail gas discharged from a lower part has lower temperature, thereby saving more energy in comparison with the prior art that the upper part of a water tank of the boiler is provided with a chimney outlet to enable the fire rear to directly run away and take away the high-temperature tail gas.

Description

technical field [0001] The invention belongs to boiling water and steam boilers of fuel burning appliances, in particular to an energy-saving opener boiler. Background technique [0002] The boilers in the prior art are all made of an arched structure, and on the side of the door of the arch structure, the exhaust gas that enters the chimney has a high temperature and is discharged to the air, causing It is quite wasteful; some are made into cylinders, and a chimney is opened on the upper part to pass through the water tank. But the fire tail is still very high, causing waste. This is because the fire tail in the high-temperature furnace is straight and rushes back to the furnace body without stopping or changing, resulting in waste. Contents of the invention [0003] The purpose of the present invention is mainly to overcome the disadvantages of the prior art boiler stove, let the chimney be directly arranged on the furnace hall or behind the furnace hall, so that the ta...
