Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating superheated steam from water require a two-stage process, resulting in high structural complexity and costs, as they involve separate devices for heating water from the liquid phase to saturated steam and then to superheated steam.
Innovation Solution
A method and device that utilize a single temperature-regulated heating tube to transform liquid-phase working medium, such as water, directly into superheated steam by controlled application of thermal energy, potentially using exhaust gas from a burner and preheating through an economizer, with real-time adjustment of thermal energy based on steam temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a two-stage process with separate water tube boiler and superheater is used, then superheated steam can be generated from water, but structural complexity and cost increase
Solution Approach 1:
The patent combines the functions of the water tube boiler and superheater into a single high-speed steam generator. The steam coil serves dual purposes: generating saturated steam from water and then superheating that steam, eliminating the need for separate boiler and superheater units while achieving the desired superheated steam output
2Temperature
If a water tube boiler with separate superheater is used, then superheated steam is produced, but manufacturing cost and assembly time increase
Solution Approach 1:
The invention integrates multiple heating functions into one compact high-speed steam generator unit. By using a single steam coil that can both generate and superheat steam, the patent reduces the number of components, simplifies manufacturing, and lowers assembly time while maintaining the capability to produce superheated steam at required temperatures
3Device complexity
If a single heating tube is used to generate superheated steam directly, then structural complexity is reduced, but control precision of thermal energy application becomes critical
Solution Approach 1:
The patent implements dynamic control of the heating process by adjusting the thermal energy input to the single steam coil based on real-time steam generation and superheating requirements. The system can modulate the heating intensity to first generate saturated steam and then continue heating to achieve the desired superheat temperature, ensuring precise temperature control throughout the process
Solution Approach 2:
The system incorporates temperature monitoring and control mechanisms that provide feedback on the steam temperature and phase state. This feedback enables automatic adjustment of the thermal energy input to the heating tube, ensuring precise control over the steam generation and superheating process while using a simplified single-tube configuration
