Your MHI Inc. blog for saving the quality of energy and quantity of water used.
To help with the COVID-19 problems, we are encouraging our customers to consider supporting front-line workers at hospitals, testing clinics, and other healthcare facilities in their fight against the Coronavirus and the COVID-19 disease it causes with innovative uses of the steam products and Airtorch® Products. We have placed many such products in the ‘Sale’ section of the MHI web store.
How many lbs. of CO2 do you notmake when you convert to electric heating?
For every 1 kWh of energy made or converted by electric methods instead of by burning carbon-containing fuel, one prevents the production of between 0.8-2lbs of CO2, depending on the type of combustible fuel replaced. Some combustible fuels contain carbon only (like coal) and some have carbon and hydrogen (like natural gas). Source: https://www.eia.gov/. This calculation does not include any greenhouse gases other than CO2.
Gases like methane are also very problematic climate gases (Source).
Simplicity is fully extended to the industrial sectors. This design philosophy is helping with MHI Inc.’s Climate and Sustainability Products.
From textured surfaces that use very little grease to reducing greenhouse gases – some examples of new technologies and SmartMachines are discussed below for Heating, Communication, Fiber-Forming, Furnaces, Fuel Production, Clean Reactions, Ultra-low friction, and many more…..
Choice of Steam Generators Choice of Pressures. Apart from the significant energy savings that MHI products offer – several additional savings are also experienced. For example, when one saves over ten psi in pressure drop, this equates to about a 30 KW savings for a 1000 SCFM flow.
The best way to increase savings and reduce emissions is to lower the power consumption and total energy use for any objective.
Lower the device power usage by just 1 kW – Save $876 per year @US 10c/KWhr (A typical US household uses 2-4 KW (power) devices at home). Multiply this power by the hours used for obtaining the energy used and price-paid.
Industrial use of power is much higher ~ 100-1000 KW are used for industrial devices, especially when radiative, steam, and materials processing requirements.
These items are now essential in a new device specification. They are best practices and should be part of your project when specifying a device.
Warranty – Ask for a Warranty on the Heating-Element for a Steam Generator, Hot Plate, Airtorch, or Furnace.
Ask for Testimonials – Or look for them on the manufacturer’s website.
Does the manufacturer provide several levels of tutorials – Online forms?
Online RFQs – Does the manufacturer provide this?
Prices: Although not always comprehensive, there should be an online web store with price guidance.
Does the manufacturer talk up energy efficiency and sustainability? It’s a good practice to ask the sales agent.
Does the manufacturer believe in Simplicity of design?
What makes a device cost more?
Here is a list of items that typically may lead to an increase in the capital cost of a device.
Short Time-Frame – The faster you need it, the more people will need to work on your order to make the deadline. More people equals more money.
Customization– Customization could be great but is costly. Please be aware that the more items are built from scratch, the higher the cost.
Spreading out payments: Paperwork from your end could take time – sometimes even compared to the build-out. Manufacturers routinely depend on being paid on time. The best prices are given when prepayment is made.
Integration to 3rd Party Tools: Choose a manufacturer that provides its data acquisition system. The third part, tools can cost money and time to integrate.
Will I get my money back? What is my ROI?
When choosing a product, ask for typical Return On Investment Calculations if you will use it to generate revenue.
Check for Testimonials and Reviews. A good manufacturer will always post these.
Is the repair policy sound, affordable and valuable? Machines will break down – maintenance is typically 10% of the initial purchase. The buyer should check if the manufacturer offers a comprehensive policy like the NeverDown(TM) guidelines.
It does not hurt if the company you are dealing with has at least two decades in existence with continuous testimonials.
Did the manufacturer or seller provide the quote promptly? If not, it could be a symptom of downstream delays. There are exceptions, but buyer beware.
Summary: There is no one answer to how to choose your best thermal device. The above are some guidelines that refer to good practices. Now include some Green Practices and obtain more benefits-
Some Benefits Of Going Green and even Blue In Manufacturing?
Attracting buyers as a way to do more business is a benefit of sustainability. How can MHI help? MHI technologies offer the potential to:
Applications of Steam Generators: From Drying Antimicrobial and Waste to Energy – Steam has many advantages e.g. reducing the amount of landfill dumping, reducing the amount of greenhouse-gas emissions and pollution, as well as reducing dependence on non-renewable fossil fuels.
If one burns fossil fuel, the best efficiency is ~50-85% for achieving a work objective. With electric energy, efficiency for an aim can be closer to 100% during conversion. Sunlight to direct electrical work is ~35-44%.
The weight of carbon dioxide per One Million BTU (293 KWhr) of burn with different fuels and processes.
The approximate price of this small amount of energy is US$30. A typical US home’s monthly electric bill is also in this order. Note for comparison that the average human exhales about~ 1 kg of carbon dioxide on an average day (about 7-9 kg a week) because human activity averages at about ~100 Watts or 341 BTU/hr of power usage (energy burn rate) .e. ~ about 200-250 lbs./ Million BTU.
An average size tree can absorb 20-25 kg of carbondioxideper year and can sequester 1000 kg of carbon dioxide by the time it reaches 40 years old. At standard pressure and 15°C (59 °F), the density of carbon dioxide gas is 1.87 kg/m3 (0.1167 lb./ft3). Therefore, for a zero-sum, one roughly needs about 8-10 active trees per human. It is estimated that there are 3.04 trillion trees in the world of about 7.7 billion people (source: greenfuture.io/nature/how-many-trees-are-in-the-world). (Please note that these are all approximate numbers and should only be used for an order of magnitude analysis). Other living species also produce CO2 and CH4 as well – do the combustion processes listed below. The estimate for animal species is itself from 8-30 Million species. Each species may comprise large numbers in them. One pound (~454 grams) of carbon dioxide gas occupies 0.2426 m3 (8.566 ft3, 64 US gallons, 243 liters). Now compare emissions from energy usage that produce CO2. Use the Airtorch®, MightySteam®, or E-Ion for zero carbon emission.

Surface Energy = Joule/m2= Newton×m/m2= Newton/m= Force/Length = Surface Tension
Metals typically 1000 mJ/m2
Ceramics typically 500 mJ/m2
Glass typically 100 mJ/m2
Soft Matter/Plastics typically 50 mJ/m2
WHAT VOLUME OF SOUND IS SAFE
Decibels measure the sound intensity (Amplitude)
Sound is energy that travels in pressure transverse waves. It can be measured in two ways: frequency and amplitude.
Frequency, reported in Hertz (Hz), measures the number of sound vibrations in one second. This corresponds to how low- or high-pitched a sound is. A child’s voice is high-frequency, for example. Health-wise, many older adults develop what’s known as high-frequency hearing loss, making it harder to hear sounds that are higher pitched.
Amplitude reported on the decibel (dB) scale measures sound pressure or forcefulness. This is the sound “volume.” The more amplitude a sound has, the louder the volume.
High Amplitude and High Frequency are a bad combination for the ear. See the chart below for safe to dangerous dB (not all sounds in the chart below are at the same frequency).
What Is the difference between dB and dBA? dB sound pressure levels are unweighted. dBA levels are “A” weighted according to the weighting curves to approximate the way the human ear hears. The conversion is not simple and is specific to the ear and recording; a 100 dB level at 100 Hz could be perceived to have a loudness equal to only 80 dB at 1000 Hz. Humans can hear about 20 Hz to 20 kHz.
