Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] As shown in the drawings, a boiler economizer includes a main body 2, a copper coil 5 is set inside the main body 2, the main body 2 communicates with the chimney 3, and its water inlet passes through a check valve 6 and a shut-off valve connected to the soft water tank 10 8. The safety valve 4 and the water pump 7 are connected, the water outlet of the copper coil pipe 5 is connected with the check valve 6 through a water pipe 11, and a thermometer 9 is installed on the water pipe.

[0011] Use the heat discharged from the boiler chimney (temperature 230°C) to heat the demineralized water to be added to the furnace to about 85°C, then add the water pump to the furnace at regular intervals according to the program, and carry out secondary heating to the boiling point. The time of this combustion process is shortened. Therefore, energy consumption is re...

Abstract

The invention discloses a boiler energy-saving device, which comprises a main body, wherein a copper coil pipe is sleeved in the main body; a water inlet of the copper coil pipe is connected with a stop valve, a safety valve and a water pump which are connected with a softened water tank through a check valve; a water outlet of the copper coil pipe is connected with the check valve through a water pipe; and a thermometer is arranged on the water pipe. The boiler energy-saving device provided by the invention has the advantages that: the structure is simple, and fuel and gas can be effectively saved, so that energy consumption is over 7.8 percent, and the cost can be saved by ** yuan per hour.

Description

technical field [0001] The invention relates to an energy-saving device, in particular to a boiler energy-saving device. Background technique [0002] Now natural gas and oil-fired clean energy boilers are replacing coal-fired boilers, but because the price of natural gas and diesel is higher than the price of coal, the operating costs of gas and oil-fired boilers will increase accordingly. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a boiler economizer, which has a simple structure and can effectively reduce energy consumption. [0004] For achieving above-mentioned purpose, technical scheme of the present invention is as follows: [0005] A boiler economizer, comprising a main body 2, a copper coil tube 5 is set in the main body 2, and its water inlet is connected with a stop valve 8 connected to a soft water tank 10, a safety valve 4, and a water pump 7 through a...
