Heat storage ball continuous heating furnace capable of being controlled in partition mode and control method thereof

Abstract

The invention relates to a heat storage ball continuous heating furnace capable of being controlled in a partition mode and a control method thereof. The heat storage ball continuous heating furnace capable of being controlled in the partition mode comprises a furnace body, an air system and a fuel gas system, wherein a plurality of groups of uniformly distributed heat storage balls are arranged on one side of the furnace body, the furnace body is sequentially divided into a plurality of temperature zones from an inlet to an outlet according to the standard from high temperature to low temperature, the air system comprises air pipelines arranged above the temperature zones correspondingly, and the fuel gas system comprises a natural gas main pipe and natural gas branch pipes leading to thetemperature zones correspondingly. According to the heat storage ball continuous heating furnace capable of being controlled in the partition mode and the control method thereof, a system is simplified, the failure rate is low, faults are easy to check, and the production cost is effectively saved; and all the temperature zones can be controlled in the partition mode so as to be independent fromone another, the air-fuel ratio is accurately adjusted, and the energy loss consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a zone-controllable heat storage bulb continuous heating furnace and a control method thereof. Background technique [0002] The principle of the regenerative continuous heating furnace is the same as that of the burner. Under the same combustion effect, the cost of the continuous heating furnace is low, and it saves gas energy. Although the advantages of the regenerative continuous heating furnace are obvious, the existing storage The thermal continuous heating furnace has the following problems: [0003] 1. The total length of the regenerative continuous heating furnace is 26cm, and the centralized control of different temperature zones results in inaccurate accuracy in each temperature zone. For example, after adjusting the air-fuel ratio in the first zone, adjust the second zone. Changes lead to fluctuations in one area, and each temperature area is always i...

AI Technical Summary

Problems solved by technology

[0003] 1. The total length of the regenerative continuous heating furnace is 26cm, and the centralized control of different temperature zones results in inaccurate accuracy in each temperature zone. For example, after adjusting the air-fuel ratio in the first zone, adjust the second zone. Changes lead to fluctuations in one area, and each temperature area is always in a state of mutual influence;

[0004] 2. It is difficult to adjust the air-fuel ratio, resulting in energy loss and consumption;

[0005] 3. When a fault occurs, the entire furnace system is completely paralyzed, it is difficult to troubleshoot faults, increase maintenance costs, prolong the production cycle, and it is difficult to guarantee safety
