Thermal Oil Steam Generator

Equipment Overview

Our company is an early developer and manufacturer of ZFQ (horizontal) and ZF (vertical) type steam generators, designed to match organic carrier heating furnaces. The specifications include a series of products from 0.1t to 12t, such as 0.2t, 0.3t, 0.5t, 0.8t, 1.0t, 1.5t, 2t, 3t, 4t, 5t, 6t, 8t, 10t, and 12t. We also offer customized design and manufacturing services based on customer requirements. The design of this product utilizes the principle of kettle-type heating and evaporation, enabling continuous or intermittent steam production according to actual operating conditions, rather than direct flame heating. The structural forms available are vertical and horizontal. This steam generator is safe, reliable, cost-effective in investment and energy, reduces operation costs, features a compact structure, and is easy to install and maintain. It is simple to operate and convenient to use, with a reliable quality. Both vertical and horizontal structural forms are available, and the design and manufacturing of the product comply with the relevant provisions of the "Safety Supervision Regulations for Pressure Vessels."

       The organic heat carrier heater is used in conjunction with our steam generator, providing not only high-temperature medium for users but also the required steam to meet production needs, expanding the range of applications. The steam generator is widely used in industries such as textile dyeing, food processing, rubber, wood processing, fats, and chemicals, fulfilling the industrial demand for mature steam with just one organic heat carrier boiler, thus saving on equipment investment and labor.

Operating Principle

       This evaporator consists of two parts: the hot oil section and the steam generator.

       The hot oil section involves high-temperature thermal oil passing through a thermal oil pump or directly from a heat carrier furnace into the tube bundle of the steam generator. The heat inside the tubes is transferred to the external pot water through the tube walls at a certain flow rate and temperature, heating the water and cooling the thermal oil, which then returns to the furnace to be reused in the cycle.

       Steam generators use softened water; preheating can increase the evaporation amount. Water enters the evaporator from the bottom, is heated naturally by convection on the heating surface, producing steam, which then passes through submersible plate and equalizing plate to become unsaturated steam, and is sent to the steam separator to supply gas for production and daily use.
