Solution Overview
Problem
Existing mobile water heaters are limited in size due to transportation regulations, making it impractical to adapt large direct contact water heaters for industrial applications that require large volumes of hot water in various locations, such as drilling and mining operations, as they exceed maximum vehicle height and width restrictions.
Innovation Solution
A mobile water heating system with multiple burners and flame tubes, designed in an oval-cylindrical shape to fit within size restrictions, utilizing a fuel tank for propane and incorporating vaporization coils and high-efficiency burners to efficiently produce large volumes of hot water while ensuring compliance with road regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large direct contact water heaters are used to produce large volumes of hot water, then hot water production capacity is improved, but the device size exceeds maximum vehicle height and width restrictions
Solution Approach 1:
The water heater is divided into multiple separate burners (first burner, second burner) with individual flame tubes, allowing the heating components to be distributed throughout the available volume rather than concentrated in a single large chamber. This segmentation enables the system to achieve large hot water production capacity while maintaining a compact overall device size that fits within transportation restrictions.
Solution Approach 2:
The patent utilizes vertical space by positioning burners and flame tubes at different heights within the shell, with the first burner and flame tube arranged vertically relative to the second burner and flame tube. This three-dimensional arrangement maximizes the heating capacity within the constrained vehicle height and width dimensions, effectively transforming a two-dimensional layout problem into a three-dimensional solution.
2Productivity
If multiple burners and flame tubes are used to increase heating capacity, then hot water production volume is improved, but device complexity increases
Solution Approach 1:
Multiple burners and flame tubes are merged into a single integrated shell structure, where each burner assembly (burner plus flame tube) functions as a modular unit. This merging approach allows the system to achieve high hot water production volume through multiple heating zones while managing complexity by consolidating all components within a unified compact housing that meets transportation size restrictions.

AI summary
Mobile water heating systems for producing hot water are disclosed herein. In one embodiment, a mobile water heating system includes a water heater having an oval-cylindrical shape. The water heater includes a shell, a lid and a water reservoir having a screen. A first heating coil and a second heating coil can extend between the screen and a first cone and a second cone, respectively. A first burner and a second burner can be configured to mix and combust fuel and air and direct the resulting flames through the heating coils. Pall rings can at least partially fill an interior volume of the water heater and the combustion of the fuel and air can heat the heating coils and the pall rings. Water can be heated by being directed through the heating coils and through a water manifold positioned to spray water on the pall rings.
