Gas-fired center fired boiler for chemical reminds you to shut off the fuel supply of the furnace immediately in case of quenching, close the electromagnetic valve for gas supply (oil and return), and then close the fuel supply valve for the operation of burners. Operate quickly so as not to cause a vicious risk when fuel continues or resumes supply. At the same time, find out the causes of boiler quenching, remove the found faults, and make preparations for restarting.

Shandong Mining Group in the six months after the fired boiler for chemical use, users submit a report to our company, our company started in 2017 using WDR0.5-0.8-Ⅱ electric fast Boiler Co., Ltd. of heating steam boiler. Large output, stable and reliable, high degree of automation, simple operation, do especially in terms of security is in place. After-sales service is very timely response to our technical consulting reply quickly and accurately. Whether it is party party products or fast fast service. My company is very satisfied. --customer feedback

However, South Africa is not credited with having coal deposits and hence, may not be in a position to maximize the benefits as coal is not an indigenous resource. By their own admission, SEG would import the coal from overseas (some have suggested that coal would be imported from South Africa) into South Africa and further transport it to the plant to be “burnt” in South Africa. This admission and subsequent action means that there is a beneficiary from the importation of coal. Given Zhengzhou Boiler ( Group) Co. Ltd credentials as a China-based company principally engaged in power plant fired boiler for chemicals, supply of gas and development of all types of energies as well as researching and investing in new energy-related technologies, I find it hard to believe that coal would be consistently and sustain-ably sourced from other countries excluding China during the entire life time of the project because (1) SEG’s has credential as a major stakeholder in coal-fired power plant and (2) China tends to ensure that we source items from them in their attempts to assist us developmentally. All these and more suggests that the benefits of this project ensure more to China.

17.5MW YQL thermal oil heater for oil refining industryThe thermal oil heater is an essential equipment in oil refining industry, providing heat energy for rectification, hydrogenation, catalysis, gasification and other production processes. Dongfang Hualong Group is a large enterprise engaged in processing and sales of petroleum, main products include gasoline, diesel, propylene, liquefied gas, slurry oil, petroleum coke, petroleum machinery, etc. With the global green development trend, oil refining industry will adjust its industrial structure on a large scale. Dongfang Hualong Group seized the opportunity to accelerate transformation and upgrading and vigorously develop the circular economy. As an important part of production line, the thermal oil heater takes the lead in achieving equipment innovation. Hualong Group planned to purchase several energy saving and environmental friendly thermal oil heater to meet the needs of the production line. Quality has always been ZOZEN’s lifeline. In the pursuit of product quality, “never compromising to quality” has always been the principle that ZOZEN carries through, this kind of craftsmanship spirit successfully earned Dongfang Hualong Group's trust. The sales manager of ZOZEN provided the company 4 sets of 17.5 MW gas/oil-fired thermal oil heaters after learning about their actual demands. The thermal oil heater has wide adaptability of fuels, is suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. It is also equipped with an advanced burner to ensure the NOx emission below 30mg/m³. The waste heat fired boiler for chemical, air pre-heater and economizer are installed on the tails of the thermal oil heaters to effectively improve thermal efficiency, which can reach above 98%.
