Combustion control system of foamed glass foaming furnace

Abstract

The invention relates to a foam glass foaming furnace combustion control system, which comprises a temperature control system, a host computer and a field control box, wherein, a foaming furnace is divided into a plurality of furnace regions; the inside of each furnace region is divided into more than one temperature region; each temperature region is respectively provided with temperature control points; various temperature control points are connected with HC900 miniature distributed controllers; an industrial control computer is taken as the host computer, is communicated with the HC900 miniature distributed controllers by combination with industrial control software, and can realize the functions of dynamic display of the state of a furnace body, dynamic display of the state of a pipeline, parameter setting, recording of history data, manual control and failure logging; the field control box is used for realizing control of manual start of each burner, realizing the functions of flame display, flame malfunction alarm and fuel shutoff, and realizing the two-way communication between the field control box and the HC900 miniature distributed controllers. The foam glass foaming furnace combustion control system realizes large-scale and intelligentized production of foam glass, low energy consumption, high quality and friendly environment.

Description

(1) Technical field [0001] The invention relates to a combustion control system of a foaming furnace for foam glass. (2) Background technology [0002] Foam glass is a kind of porous glass, which is a glass product filled with countless tiny pores, that is, a uniform gas and solid phase system. Its pores account for 80%-90% of the total volume, and the size of the pores is 0.5-1.0mm. In the 1930s, the French St.Gobain company began to develop foam glass products with calcium carbonate as the foaming agent. In 1935, it applied for the first At the same time, the former Soviet Union also developed foam glass. In 1939, foam glass products were produced in the intermediate pilot plant of Mendeleev Institute of Chemical Technology. Subsequently, the United States, Germany, the former Soviet Union, the United Kingdom, the Czech Republic, Japan and other countries published many patents and research reports on the development and production of foam glass. In 1941, Pittsburgh-Corn...

Problems solved by technology

At present, electric energy is generally used as the heating method at home and abroad. Although the temperature in the heating furnace can be controlled, the cost is high, and the temperature uniformity in the furnace is poor, the quality of the product fluctuates greatly, and the production volume is low.

Although there are also attempts to use gas heating at home and abroad, due to the difficulty in mastering the foaming temperature zone control, the quality of the product fluctuates greatly, and it is difficult to achieve a substantial increase in production.
