7MW YQW series gas-fired thermal oil heater for chemical industryAs one piece of important equipment for the water purification material production line, the thermal oil heater plays the role of providing heat energy in the production process of the water purification agent. Chongqing Lanjie Guangshun Water Purification Materials Co., Ltd. was established in 2009, mainly producing and selling industrial water chemical treatment agents and urban sewage chemical treatment agents. With the continuous expansion of production scale, the company urgently needed to upgrade the boiler equipment on the existing production line. Meanwhile, in the face of increasingly severe environmental pressures, the company decided to purchase environmentally friendly thermal oil heater which uses clean energy natural gas as fuel. In the market research process, the project manager of the company found that the ZOZEN thermal oil heater had outstanding advantages in terms of product quality, performance and environmental protection effects, then the company decided to purchase a set of 7MW horizontal gas-fired thermal oil heater from ZOZEN. This kind of heater adopts three pass circular tube design for sufficient heating surface, and the waste heat boiler and energy-saving device disposed at the tail of the heater can greatly reduce the loss of thermal energy, the thermal efficiency can be as high as 95% or more. Advanced low NOx burner can achieve NOx emissions below 30mg/Nm³. And the operation of the thermal oil heater can realize full automatic control, and can automatically adjust the combustion, high tank level, outlet temperature and flow to ensure the safe operation.

Henan run several areas, including Henan gas boiler gas boiler operation includes several aspects: daily monitoring and adjustment operations; accident treatment; start and stop; optimal operation mode and technology improvements. When the normal operation of the boiler, the daily operation of the monitoring and adjustment of the operating accounts for the major part. "Stable" is the key, pressure, temperature, water level, negative pressure, milling parameters, etc., remain stable conditions is an important guarantee for safe and economic operation. Briefly, the steady working primarily by "balancing" the means to obtain, for example, outside the furnace combustion conditions and load balance, the pressure is stable; to balance the amount of water and evaporation, is stable water level; primer with the supply air volume the amount of negative pressure equilibrium is stable, according to Henan gas boiler operation adjustment purposes, and in accordance with the purpose of regulating the boiler operation, to take the necessary means of regulation. Daily adjustment of the key - "steam pressure." Among the major parameters of Henan gas boiler, main steam pressure to maintain stability is the key which only the steam pressure is stable, the remaining parameters to stabilize. Unstable steam pressure, steam temperature, the water level will also change, so first of all start from the pressure adjustment. Vapor pressure is divided into an outer and an inner interference disturbance, our plant, i.e. outside the external disturbance load generally little change, so change in vapor pressure are changed within the furnace i.e. interference caused by operating conditions, so holding furnace combustion conditions the stability is the stability of the vapor pressure. If the combustion conditions change, such as wind than powder, coal calorific value and other factors change, a pressure change occurs, requires us to be adjusted, thereby changing into a stable state of the combustion furnace transient state conditions.

How to choose the right boiler steam solenoid valve tips? Solenoid valve is used to control automation infrastructure element the direction of flow, is actuator; commonly used in industrial machinery and control valves used to control the direction of the medium, so as to achieve the vapor solenoid valve control solenoid valve switch operating principle of the currently used usually over two steam: 1, steam boilers - saturated steam temperature and pressure is relatively stable at temperatures below 250 deg.] C, lower than the working pressure 1.6Mp. It can be widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and research departments as well as bathrooms, dining room, air conditioning and other automatic control system. 2, out of the steam power plant - superheated steam temperature high base pressure changes, temperature up to 400 or more, lower than the working pressure 4.0Mpa. Typically use seal steam solenoid valve broader generic media can be used separately in water, light oil, heavy oil, non-corrosive fluid such as gas and steam. The exhaust system of plant extraction duct draining system and an evaporator, the main medium in the pipeline and a remote two-position automatic adjustment control.
