2.4MW YQW gas-fired thermal oil heater for textile industryThermal oil heaters play an important role in the textile industry, providing heat energy for the process of dyeing, drying and printing. Located in Manila (the capital of the Philippines), Pantone Finishing Corporation is a large company engaged in textile products. The rising in natural gas price results in the increases of running cost for original thermal oil heaters. In order to save cost while having no effect on production, the company planned to purchase several energy-saving thermal oil heaters. The thermal oil heater produced by ZOZEN has superior  advantages in manufacturing technique, which will guarantee the high quality. In consideration of the actual condition, ZOZEN’s engineer provided the company with YQW series gas-fired thermal oil heater and a tailored-made solution. The thermal oil heater adopts multi-loop coil tube design for safe operation, sufficient heating surface and high thermal efficiency. Furthermore,  to achieve maximum effect of energy saving and consumption reduction, the thermal oil heaters are also equipped with waste heat recovery device including heat recovery 10t boiler high efficiency hot selling turkey, air pre-heater and economizer. The textile mill was so satisfied with the solution that they ordered several thermal oil heaters.

Low nitrogen 10t boiler high efficiency hot selling turkey and classification of meaning: In recent years, the state vigorously promote clean air plan, Yajian coal. Whether the use of coal-fired central heating boilers, and rural small coal stove for cooking and heating, are gradually being clean energy alternatives under the relevant policy. Thus, in recent years, sulfur dioxide, dust content in the atmosphere continues to decline. But it is worth noting that more and more use of natural gas, also caused a certain amount of nitrogen oxide pollution. Use low nitrogen boiler of the environmental benefits of very large.

As the "Star Pavilion" on the show, the arrival of fast 10t boiler high efficiency hot selling turkey is attracted quite a stir. Guests and friends from all over the world friends are gathered in front of "fast Boiler" booth, feeling the charm to bring clean boiler. This is the third appearance in the fast side of the trade show, our booth set up in the middle of the field, in the light against the background, beautiful booth set off for the scene of different merchants brought extraordinary appeal.
