Usable, Sustainable Electricity From Waste Heat

Posted by H&P Blog on Wed, Aug 07, 2013 @ 10:04 AM

Heat is generated by electrical equipment and industrial processes every day, unintentionally bleeding off into the atmosphere.  This waste heat often involves the combustion of fuels, and occurs in the largest proportions from power stations, industrial plants and vehicle engines.  It is inevitable that some of this heat will be lost, but much of it can still be utilized.  It can be used for the majority of heating applications, but unlike electricity or fuel energy, it is impractical to transport over long distances.

Lignite Drying Process Means Cleaner Fuel and Increased Efficiency

Posted by H&P Blog on Wed, Mar 27, 2013 @ 11:55 AM

Lignite is a brownish black combustible mineral that formed over millions of years by the partial decomposition of plant material, while it was subjected to high pressures and temperatures in an airless atmosphere.  In simple terms, lignite is a form of coal.  North America's lignite reserves were deposited by massive quantities of dead and decaying plants in a swampy atmosphere 50 to 70 million years ago, and runoff from the newly formed Rocky Mountains buried them under tons soil and rock.

Clean Coal Could be the Solution to Global Warming

Posted by H&P Blog on Wed, Mar 06, 2013 @ 11:10 AM

Much has been made of the recent development by Ohio State University into clean coal processing technology.  This effort utilizes an innovative process called "chemical looping."  Typical coal-fired power plants burn coal to heat water, which makes steam, which then turns the turbines that produce electricity.  In chemical looping, coal isn't burned with fire, but instead is chemically combusted within a sealed chamber so it does not pollute the air.

Factors to Consider in Selecting Industrial Drying Equipment

Posted by H&P Blog on Wed, Dec 05, 2012 @ 10:46 AM

Because an industrial dryer is a major capital investment for any organization, it pays to select and test the unit carefully.  Dryer life can be measured in decades, so the selection of inefficient equipment can have a long-term impact on the economic health of the facility that houses it.  The selection of drying equipment is predominantly an exercise in which knowledge, experience and science all play important roles.  Because of the complexity of the drying process, many factors need to be considered and weighed.

Waste Heat Powers Industrial Processes for Continual Sustainability

Posted by H&P Blog on Wed, May 30, 2012 @ 11:15 AM

Heat is generated by electrical equipment and industrial processes, and unintentionally leaks into the atmosphere because no useful application is found for it.  This waste heat often involves the combustion of fuels, and is also commonly referred to as secondary or low-grade heat.  The largest proportions of waste heat originate from power stations, industrial plants and even vehicle engines.  This heat is useful for the majority of heating applications, but unlike electricity or fuel energy, it is impractical to transport over long distances.

Rotary Dryers: Direct Drying vs. Indirect Drying

Posted by H&P Blog on Wed, Dec 28, 2011 @ 09:22 AM

One of the most important factors in determining what type of Rotary Dryer is right for a certain process is the usage of direct or indirect heat.  Rotary Dryers are capable of utilizing either direct convection style heat transfer or indirect heat transfer, in which hot surfaces within the dryer provide heat by conduction and radiation.  The determination of direct or indirect drying is contingent on the properties of the material to be dried, the process conditions and the desired end product.

Determining Specifications for a Rotary Dryer

Posted by H&P Blog on Wed, Dec 21, 2011 @ 11:00 AM

Rotary Dryers are the most versatile dryers available.  For continuous drying of bulk solids, they excel in their ability to handle a very broad range of materials regardless of their conveying and handling characteristics.  Whether a process requires the drying of fine dusty powders, lumpy solids, sticky semi-plastics, pellets, agglomerates or even a mixture of all of those, there is a Rotary Dryer that will accomplish the task successfully.

The Anatomy of a Rotary Dryer

Posted by H&P Blog on Thu, Dec 15, 2011 @ 12:53 PM

A Rotary Dryer is a type of industrial drying equipment that reduces or minimizes the moisture content of the material it handles by bringing it into direct contact with a heated gas.  As manufactured by Heyl & Patterson, this type of dryer is suitable for materials ranging from minerals and metallurgical ores to chemicals and fertilizers to grains and cereals, as well as paper pulp, pigments, biomass, coal, oil sands and soil remediate.

Heyl & Patterson to Exhibit at Power-Gen International

Posted by H&P Blog on Tue, Nov 22, 2011 @ 12:25 PM

Power generation comes from a variety of heat-producing sources: oil, natural gas, nuclear, geothermal, wind, solar and of course, coal.  The heat boils water and creates steam.  The steam, under high pressure, spins a turbine.  The turbine interacts with a series of magnets to produce electricity, which is transmitted as moving electrons through a series of wires to homes and businesses.
