Thermal oil boiler is a kind of essential equipment in the chemical industry, which plays a role in providing heat energy in production processes such as distillation, rectification, and hydrorefining. The cooperation with Xinli Boiler this time is a chemical enterprise that mainly produces synthetic resins, organic pigments and other products. Its production process requires a stable heat source of 200 ℃~280 ℃ continuously. The original heating system of the enterprise used traditional coal-fired steam boilers, which had multiple pain points, such as insufficient thermal efficiency (only about 65%), serious coal waste, and large heat loss in steam pipelines. Due to the increasing global awareness of environmental protection, the company decided to replace their traditional coal fired steam boiler with an environmentally friendly thermal oil boiler . They got that Xinli Boiler has unique process for producing this kind of product after multiple investigations and research. Xinli Boiler has outstanding advantages in ensuring boiler quality and improving environmental protection effects, and has also established a good reputation in various industries. Therefore, the company chose Xinli Boiler as its new boiler supplier for the renovation of the heating system. The customer purchased a Xinli Boiler's 7000kw horizontal coal-fired thermal oil boiler (YFW-7000H) as their core equipment for their chemical production based on the recommendation of Xinli Boiler's sales manager .

Xinli Boiler's YFW series coal fired thermal oil heater is a horizontal square box organic heat carrier boiler that uses coal as the heat source. The boiler is mainly composed of the boiler body, coal-fired system, circulation system, control system, etc. The cost of this coal fired boiler is low and some new designs combined with flue gas waste heat recovery devices (such as economizers) can effectively improve thermal efficiency. This thermal oil heater can provide stable high temperatures above 300 ℃ (up to 350 ℃), which meet the requirements of high-temperature processes such as polymerization, distillation, and reactor heating in chemical production, and avoid safety risks of steam boilers under high pressure.The thermal oil boiler system can be operated at normal pressure without the need for high-pressure vessels (such as steam boilers that require special equipment supervision), reducing electricity consumption and maintenance costs. This YFW series coal fired thermal oil boiler from Xinli Boiler can also be operated in parallel with multiple units. It can be flexibly started and stopped according to production load, that avoid energy waste caused by "big horses pulling small cars". This is also one of the important reasons why the customer purchased 4 units of YFW series coal fired boilers from Xinli Boiler at once. In addition, the boiler adopts an integrated PLC control system to monitor parameters such as oil temperature, flow rate, and pressure in real time, and diagnose faults automatically, thereby reducing the need for manual intervention. The use of these boilers can assist this enterprise in achieving 24-hour continuous and stable heating to avoid losses from steam system start-up and shutdown.
