Description of Product

For more than twenty years, the heat-transferred media boiler has found the wide application in textile printing and dyeing, chemical industry, artificial leather, building mateiral industries. However, its high return oil temperature with 200 ~ 250℃ causes the high funnel temperature of boiler. In general, it reaches 300 ~ 350℃ . Thus a large amount of calorific capacity is exhausted into atomospher. In the time when energy shortage is a very serious problem and the price of energy rises in the world, energy saving and environmental protection is the urgent needs for sustained development in many countries.
Changzhou Zongyan has addressed itself to the comprehensive utilization of energy source and would like to provide utilization scheme and project of multile low temperature exhaust heat.

The pressure of heat recovery boiler is 0.7 – 2.5MPa. The evaporation rate is determined in accordance with the waste heat from flue gas. The form and structure of boiler can be designed and manufactured in accordance with user’s site and the requirement of design institute.
