The sealing and heat insulation structure of each part achieves the purpose of energy saving and consumption reduction.
Our company's thermal power branch has a total of six 130t / h medium pressure pulverized coal boilers. Insulation original design for the top seal: adding celite refractory concrete panels sealed insulation material. After 1 year of use, the ash leakage in various parts of the top of the furnace is serious; the new material such as aluminum silicate board and high temperature adhesive is used for sealing and heat preservation. Although the situation has improved, the effect is still not satisfactory. To this end, we made further refined and improved insulation to seal program.
A seal options 1.1 aluminosilicate refractory fiber of aluminosilicate refractory fiber insulation material has the following characteristics: high temperature, light and soft, low thermal conductivity, good thermal stability, low thermal expansion, elastic, heat may not be considered at room temperature Stress problems, hot and cold sudden changes will not break, is a good material for boiler sealing and insulation.
Thermal conductivity (20 highest temperature, C 1000 1.2 high temperature micro-expansion plastic) It is a neutral, plastic refractory material. Small bulk density, soft and plastic at room temperature; micro-expansion at high temperature; high pressure and flexural strength after high temperature; toxic, non-corrosive; it does not burn, easy construction, without on-site formwork.
Main technical parameters: bending strength after drying (10±8 post-compressive compressive strength, MPa 12 220,000.
h meter, the section of electricity 128,000 yuan.
After the bellows heat exchanger was put into production and operation in June 2001, various production process indicators met the design requirements. Compared with the original tube heat exchanger, the heat transfer effect is greatly improved, the system operating pressure is reduced by 0.09 MPa, the dosage is increased, and the annual water saving, electricity and multi-production ammonium chloride value is 1.255 million yuan. And to ensure the full load safe operation of production, the comprehensive benefits are obvious, in short, the bellows heat exchanger is a better energy-saving equipment in chemical production.
