What are polymers in technology?

Polymer Technology can be described in brief as the manufacture, processing, analysis and application of long chain molecules. Materials that are typically classified as polymers include: plastics, paints, rubber, foams, adhesives, sealants, varnishes and many more.

What is natural draft furnace?

July 24, 2020. A furnace with natural airflow around it that supports combustion. It depends on the pressure that heat creates in the flue gases to force them out through the vent system.

What do polymer technologist do?

Polymer technologists are involved in the design and development of new materials, technology and manufacturing processes that use polymers. They have particular responsibility for developing the moulds used to form the material during manufacture.

What are 7 technological systems?

What type of heating system is best?

In general, furnaces are the most efficient of the heating systems, especially if you have natural gas. They work by heating air with a component called a heat exchanger and pushing it into the home through a duct system, using a fan (often referred to as a blower).

What is the fertilizer industry?

The fertilizer industry is made up of companies who represent the entire supply chain from production to distribution to retail, all working together to deliver fertilizer to farmers in a safe, timely, and sustainable manner.

Is fertilizer a technological innovation?

Technology may be defined as techniques, skills, methods and processes used in the production of any good or service. Everyone is aware of the fact that technology is changing rapidly. At one time, the addition of fertilizer to a crop was a new technological advancement.

How do furnaces work?

Natural gas or propane is ignited in the burner. The flames heat up a metal heat exchanger and exhaust out of the flue. The heat exchanger transfers its heat to the incoming air. The furnace's blower forces the heated air into the ductwork and distributes it throughout the home.

What is the best topic for computer?

Latest Topics for Pursuing Research in Technology and Computer science 2018-2020

  • Role of human-computer interaction.
  • AI and robotics.
  • Software engineering and programming.
  • High-performance computing.
  • Geo informational systems, databases, and data mining.
  • Compiler optimization and embedded systems.

How do furnaces save energy?

A high-efficiency furnace saves money because of two major developments in furnace technology: They have two heat exchangers instead of one, so the condensed gas is converted into heat instead of being expelled through the exhaust as in older models.

Is gas heat a furnace?

A gas furnace is a home heating appliance that runs off of natural gas. The natural gas is ignited in the furnace, warming up the air, which is then delivered throughout the home. A fully functioning gas furnace requires all of its components to be working in sync.

What is technology with example?

Technology is the application of scientific knowledge to the practical aims of human life or, as it is sometimes phrased, to the change and manipulation of the human environment.

Why furnace is used?

A furnace is a device that produces heat. Not only are furnaces used in the home for warmth, they are used in industry for a variety of purposes such as making steel and heat treating of materials to change their molecular structure. Central heating with a furnace is an idea that is centuries old.
