Summary In this paper,
three methods of heating gas boiler investment, operating costs, per unit area
heating gas consumption and pollutant emissions, a comprehensive comparison.
Results of the comparison surface, the user should be given priority on the
residents use heating gas boiler wall, public buildings and commercial
buildings should be given priority use of modular gas boiler heating, gas
boiler heating region has to be spread, so most provincial natural gas
consumption, pollutant emissions, at least, run lowest cost.
Introduction With the
restructuring of urban energy, natural gas has become an important energy
heating gas boiler heating. Divided into the following three forms:
single-family home heating gas boiler, gas boiler heating distributed,
centralized regional gas
boiler heating, hot water heating is generally used.
Second, natural gas
heating single-family Domestic gas boiler heating is to each household as a
unit, using domestic gas boiler heating. Domestic gas-fired boiler for heating,
bathing and water, are multi-type gas appliances.
1 Features Advantages:
high efficiency domestic gas boilers, features and more. 1 1 as a system, while
addressing the heating and hot water supply. Single-family gas hot water
heating has great flexibility in the regulation of the use of completely independent,
self-heating temperature can be adjusted, self-heating time can be controlled
freely from room to room temperature control, no boiler room and outside the
network of thermal heat loss, saving of foreign net capital investment.
Consistent with the principle of charging according to the heat can be
accurately measured gas consumption, gas consumption by the user
independent control, with such high efficiency heating system (usually 90%),
avoiding the central heating energy caused by an area of transition charges
waste, which can promote the conservation of gas, so as to promote the use of
clean fuels and create high-quality conditions. At the same time heating cycle,
low power consumption to save energy and improve the utilization and use of gas
pipeline cost.
Problem: the current
domestic gas stove in the promotion of use, quality standards are not unified,
perfect after-sales service, affecting the user's normal use; gas emissions is
generally disorganized, resulting in local pollution; part of the operation of
noisy gas furnace ; in cold northern areas much trouble to the user long-term
freezing out; people are worried about their safety also.
2 heat consumption
Domestic gas boiler heating efficiency of single-family owners, no heat waste.
According to Beijing, Tianjin, sample survey, single-family heating gas
consumption index for the 7 ~ 8m 3 / M 2 . Gas consumption of the main building
impact indicators causes indoor temperatures to maintain the insulating
properties and sealing, construction of the wall to the size, heating system
operation mode and adjust the thermal efficiency of boilers, gas heating gas
consumption than the other two methods.
3 Uses Way that heating
is suitable for residential areas. During operation, the user requirements
according to their own control heating temperature and run time, to carry out
metering, save gas, while providing sanitary hot water, reduce emissions and
lower operating costs.
Third, scattered gas
boiler heating Dispersed into modular gas boiler heating heating heating and
dispersion concentration, a construction unit, a building used as a gas boiler
heating heating module (also known as cell-type gas heating). The use of
multiple adjacent properties of the same room with a gas boiler room building
called the distributed heating central heating, a heating network is
characterized by a direct supply.
