Temperature-controllable fuel boiler

Abstract

The invention discloses a temperature-controllable fuel boiler. The temperature-controllable fuel boiler comprises a boiler body and a PLC controller controlling a working state of the boiler body, wherein a hearth for storing a burner and a water storage box for storing water are arranged in the boiler body, and the top of the boiler body is provided with a smoke tube communicated with the hearth; the bottom side wall of the boiler body is provided with a hot water faucet communicated with a hot water outlet of the water storage box by virtue of a hot water outlet pipe; and a water supplementing box is also arranged by the side of the boiler body, a coil pipe for cooling the boiled water delivered by the boiler body is arranged in the water supplementing box, a water inlet of the coil pipe is communicated with a hot water outlet of the water storage box by virtue of a hot water pipeline, the water outlet of the coil pipe is communicated to a warm water faucet on the bottom side wall of the boiler body by virtue of a warm water pipe, and the warm water pipe is provided with a water pump and an electromagnetic valve connected with the output end of the PLC controller. The controllable temperature fuel boiler integrally controls the ignition, burning and monitoring, realizes the accurate temperature control, can improve the heating efficiency and self-sustaining capability, and can reduce the energy consumption.

Description

Technical field [0001] The invention relates to the technical field of boiling water furnaces, in particular to an oil-fired boiling water furnace. Background technique [0002] Boiling water boilers are water heating equipment designed and developed to meet the drinking water needs of all kinds of people. Common water boilers include electric water boilers, oil-fired water boilers, gas-fired water boilers, and coal-fired water boilers. Oil-fired water boilers use oil to obtain heat. Equipment to heat water. [0003] Traditional oil-fired boiling water boilers usually adopt a vertical oil-fired boiler structure. This boiler is composed of a burner, a furnace and a water tank. The water tank is vertically equipped with a direct fire tube. The lower part of the direct fire tube is connected to the furnace, and the upper part is connected to the chimney. The water tank outside the tube is filled with water, the heat generated by the burner is discharged from the chimney through the s...

AI Technical Summary

Problems solved by technology

This kind of oil-fired boiling water boiler has a large volume and has the following disadvantages: 1) Since the direct fire pipes are mostly vertically arranged, the water in the water tank directly exchanges heat and cold during the heating process, and the chimney exhausts the direct fire pipes The function makes the direct fire pipe directly exchange heat and cold between the upper and lower water during the heating process. In addition, the chimney exhausts the direct fire pipe. The water boiled for a long time before the water below reached the boiling temperature, and the fuel consumption was too much; 2) Since the straight fire pipe is arranged vertically, the high-temperature flue gas generated by the burner will be directly discharged from the chimney, which not only causes heat loss loss, and the high flue gas temperature can lead to cracking of the direct fire pipe and the water tank; 3) Since the water in the water tank is in a boiling state after being boiled, if you want to drink warm water, you can only mix it with cold or hot water Obtained in a natural and cool way, which affects people's drinking needs; 4) It is impossible to detect the formation of scale in the water tank, which affects the heating efficiency
