Measuring Steam Energy and Evaluating Important Design and Installation Considerations
It is easy enough to experience steam; simply boiling water will produce it. Most steamers on the market are simply water boilers and condenser allowing steam to flow through a channel in order to direct steam vapors to an outlet or directing source. Steam is difficult to measure accurately, mainly because of its sensitivity to changes in temperature and pressure. Steam is often classified into three types, which reflect the different pressure and temperature conditions that steam is subject to.
Wet steam contains steam and condensed water. The amount of water in wet steam is designated by the term quality. The quality of steam refers to the percent of steam flow that is steam and water by weight. Steam that is 90% steam and 10% water is known as 90% quality steam. Wet steam is the most difficult type of steam to measure, and it is also known as quality steam.
Saturated steam exists at one pressure and corresponding temperature, and it does not contain any water. Saturated steam is saturated with heat. If heat is added to saturated steam, the temperature of the steam is increased above the boiling point. If heat is removed from saturated steam, condensation occurs, and the fluid becomes quality steam.
The P.O.D. Pressure on Demand Steamer system was created for a purposeful delivery of a “Extremely High Percent Quality Steam” (also known as EHPQS) to be delivered a specified distance and produce a combination of steam type, temperature, and velocity necessary to be most effective in various types of vehicle film application and removal techniques as required by the various manufactures specifications and supernatural conditions of use or exposure vehicle films receive over an applied lifetime (life expectancy of the vehicle films).
In an effort to keep cost down, we sourced components (when and where available) from local or known sources and may therefore be why the P.O.D. Steamer resembles the size, shape, weight and even sometimes the color of some of its components or overall look. It is the math and science that makes all the difference in the world in both cost and production and what sets the P.O.D. Steamer apart from any other over-the counter or commercial use Steamer!
Steam flow measurement
Most steam flow measurement happens either with differential pressure (DP) flowmeters or with vortex meters. DP flowmeters consist of a DP flow transmitter together with a primary element. The primary element creates a constriction in the flowstream, resulting in a reduction in pressure downstream from the primary element. The DP flow transmitter senses the difference in pressure upstream and downstream from the primary element, and uses this value to compute flow rate. Bernoulli's Principle is used to perform this calculation.The most common type of primary element used in flow measurement is the orifice plate. Orifice plates are also widely used for measuring steam flow. However, other types of primary elements are also used. Flow nozzles work well with steam flow measurement because they can readily handle the high velocities and pressures associated with steam flow. Other types of primary elements used to measure steam flow include Venturis and averaging Pitot tubes.
Vortex flowmeters are also used to measure steam flow. Vortex meters work well because they cause minimal pressure loss and can tolerate high temperatures and pressures common in steam flow. In distilled water heating, a volumetric vortex meter is often combined with a pressure transmitter and temperature sensor. A flow computer uses these values to compute mass flow. Multivariable vortex meters measure volumetric flow, pressure, and temperature, and use these values to calculate mass flow. Multivariable vortex meters are a fast-growing product segment within vortex flowmeters.
P.O.D. Pressure On Demand reserves the right to keep our science and math proprietary but uses all 3 measurement types in the development and testing of our production units for sale now. The P.O. D. Pressure on Demand steamer has developed a unique and specific way to heat, transfer and deliver distilled water into steam and out through a further patented series of tips and heads to give a specific temperature and velocity of steam in a specific vortex process from the body of the machine through the unique size and length of hose consistently every time.
P.O.D. Pressure On Demand even focused on the density of our produced steam:
Specifics of our evaluations for production:
• Multivariable vs. Discreet Components
• Internal vs User Installation Requirements
The frequency of the vortices is directly proportional to the velocity of the fluid.
• System use, demand and shutdown required?
• Pressure drop
As you can see there is a lot to consider when creating and building both a steam machine specific to the target industry plus creating it at a cost acceptable to the industry it is serving. The look of the machine and the cost of the machine mean nothing compared to the functionality of the machine. Most OTC machines will start looking alike or similar as component manufactures are limited and being consolidated through acquisition now days. To make sure costs are “at best”, at manufacturing time, components can come from existing component manufactures rather than every item be custom manufactured. Minimal modifications for the P.O.D. Pressure On Demand system to achieve our own specification will still incur additional costs. The last test will be the users and their acceptance of the product and its functionality specific for their needs (F.A. B. Features, Advantages and Benefits) and the overall cost vs time savings, reduced costs in other areas of the job it is performing.
