the horizontal double wall boiler
The role of factors affect gas thermal efficiency of gas heating the horizontal double wall boiler heating boiler is used to provide heat, so running the boiler thermal efficiency improvement is more important. So what specific aspects were raised from its thermal efficiency depends on the factors affecting. 1. That heat loss during operation of the boiler, furnace or the flue leakage due severe heat away, boiler fouling, and the like will affect the heat transfer portion of reduced thermal efficiency; air leakage while the boiler, the wind is not blowing rational, resulting in the excess air ratio is too large, heat losses will result in reduced thermal efficiency. 2. Low fuel is not completely burned it possible temperature in the furnace, boiler configuration and low factors leading to incomplete combustion of fuel, fuel burn rate is low, it means that the waste portion of the fuel, the heat has not been fully utilized, will still affect boiler thermal efficiency. 3. Since the materials and insulation measures are not in place, resulting in poor boiler insulation effect, the loss of thermal efficiency. Of course, factors affecting the thermal efficiency of the boiler is far more than that, it's just part of it, then the process gas used in heating boilers must pay attention to this, to ensure the safe operation of the boiler efficiency of energy consumption.
What is considered to meet the criteria of a good gas the horizontal double wall boiler it?
First, manufacturing materials
V. Installation piping, valves, instruments and accessories
1, the instrument installation should be verified, be installed in the piping, valves, instrumentation drawings, energize the electric pump commissioning.
2, the safety valve should be installed after the hydrostatic test, the safety valve should be installed exhaust pipe, the exhaust pipe should be through the outdoor security. Exhaust pipe should be installed in the bottom of the drainage pipe connected to a place of safety. Valve shall be installed on the exhaust pipe and drainage pipe.
3, each of the sewage outfall should be connected to tank or other security, the pipe should be secured to prevent shifting or counter the occurrence of injuries blowdown.
4, the main pipe by the use of units other than the mating valve, the pipeline need to consider the thermal expansion, thermal insulation pipe wall should be.
5, the dial face pressure gauge should be correct, depending on the ease of reading and rinsing; draw red dial face, the boiler shown MAWP, rotating flexible plug should not be leaking, to smooth hydrophobic Table pipe insulation prohibited.
6, only for the manufacturer pipe valve instrument (within the range shown) or the like, the other parts of the users themselves straight pipe. If you have not ordered instrument valves, the factory produced only manufacturer to install non-national standard parts required.
Pushing new fast the horizontal double wall boiler - a low nitrogen vacuum boiler "APH the T7" heavy starting at the show, numerous suction eye. "Thalia T7" launch, breaking the old burners + furnace construction mode, rational arrangement of low nitrogen burners, coupled with the furnace scientific, greatly enhance the operational efficiency of the boiler, the real "coupled," "burning "Tiancheng.
