Infrared radiation heating principle and characteristics of
China's abundant natural gas resources, with the national energy strategy,
technology transfer and the exploration and exploitation of the continuous
development of western China in recent years proven and successful development of a
number of high-quality natural gas fields, has been the formation of the Tarim,
Qaidam, Shaanxi-Gansu-Ningxia and Sichuan, Chongqing, four natural gas fields at
national level, already the basis for the development of gas industry and conditions. It
is reported that natural gas as a clean and efficient energy and high-quality chemical
raw materials, energy structure in the world the proportion has reached 24%, while in
China, the current energy mix of natural gas in the proportion of only 2.2%.
According to China National Petroleum Corporation in 2000, Zheng Hu, deputy
general manager of China International Oil and Gas Conference news conference that
China has been the development and utilization of natural gas for the early 21st
century energy structure optimization and upgrading of the oil industry focus, for ten
years about the time, so that natural gas in China's energy consumption structure in
the proportion from the current 2.2% to 8%, Tarim Basin in Xinjiang as the country's
largest natural gas fields and the birth of the implementation of the project, together
with the development of offshore oil and natural gas and natural gas abroad, including
the use of 2010 is expected to achieve this objective. Is no doubt that to develop the
national situation, the natural gas industry, natural gas as a clean energy in industrial
production and national life in the proportion of energy consumption will grow.
Under such circumstances, how to respond to national policy to better promote the
natural gas industry in the application of HVAC problems, is facing the industry,
especially in the HVAC equipment manufacturers, sales staff and design business
before an issue.
First, the principle of infrared radiation heating.
Gas-fired infrared radiant heating system consists of one or more independent
vacuum system. Each vacuum system includes a vacuum control system, a certain
number of generators and heat exchangers. Heat exchanger system of steel pipes from
100mm diameter pipeline linking and coverage of the above in its high-performance
aluminum alloy constitutes a sounding board. The system uses natural gas, liquefied
petroleum gas or gas-gas heat and combustion by the generator, the heat generator in
the air, through the use of centrifugal fans or pumps the role of the heated air and
combustion products of the radiation transport tube, radiant tube heated to a certain
temperature, produce far-infrared radiant tube outside heat transfer. The system is based on the sun heating the Earth's surface created by the principles of design, supply
of solar energy to the Earth's analysis concluded that the electromagnetic spectrum:
wavelength 10 - 8 microns (μm) below for the cosmic rays, wavelength in more than
5 × 108μm for the sound to wave, thermal radiation mainly in the wavelength range of
2 - 10μm between. The simulation of the solar system can produce only by radiation
and heat conduction medium of air) for some non-thermal heating of the radiation
(wavelength 2 - 12μm). Therefore, the direct heating of the system object space rather
than heating the air, but heating objects: space, staff, equipment, tools. These heating
objects in accordance with its own characteristics of physical and chemical structure
to absorb and store energy received, and then exposed to air through its surface to the
air space heating heat transfer, which can solve the technology sector has been beset
all HVAC kinds of military, civilian tall warehouse space heating and other problems.
Infrared radiant heating is similar to solar radiation, infrared is the part of the
electromagnetic paragraph. Different wavelengths of the electromagnetic waves are
exposed to the objects will produce different effects. Wavelength such as
0.76-1000um between the electromagnetic wave, especially in the wavelength range
of 0.76-40um, with a non-dispersive and thus the energy concentration of a significant
thermal effect, that is, infra-red. The sun heating the earth's surface with different
heating radiator, it does not require heating the atmosphere, but by solar radiation to
directly heat the Earth's surface. Through infrared radiation, radiation to the region of
direct heating, thermal radiation can be of concrete floors, and absorbed a variety of
objects, and a second radiation of these objects in order to heat other objects around.
