The high-efficiency (HE) boilers achieved energy savings overall of around 18 per cent compared with conventional boilers. However, it was shown that an unadjusted radiator system can raise heating costs by 30 per cent with HE boilers. After such adjustment, and after modifying the regulating ...
Not only electricity-driven heat pumps, but also other types of heat pumps can be coupled to condensing boilers. In comparison with an individual boiler thermal efficiency, a heat pump-boiler system fed by a low temperature heat source can reach up to 120% thermal efficiencies by coupling the...
energy market crisis has caused high prices. With the market more stable, though, suppliers are offering affordable fixed energy deals again. You may still wish to stay on a standard variable energy tariff if you're on one. For price certainty, run an energy comparison to find a better ...
A boiler operates under dynamic conditions, so it essential to know the methodology and the model of annual operating efficiency calculation for thermo technical systems. The outlet temperature of the flue gases with conventional gas boilers is considerably higher than the ambient temperature and ...
But even in traditional systems designed to work at high temperature, seasonal efficiency is also considerably increased with the use of condensing boilers. Fig. 5.14 shows the outgoing and return water flow temperature in a heating system as a function of the outside temperature. As can be seen...
The efficiency of utilization of exhaust gas heat in exhaust boilers (EGB) depends on their temperature at the outlet of EGB, id est. the depth of heat utilization. Exhaust gas temperature is limited by the rate of low-temperature corrosion (LTC), which reaches a level of 1.2 mm/year ...
British Gas offers customers energy-efficient boilers or, for those who want to take the extra step to getting a greener home, air source heat pumps. It also provides solar panel and home battery installation for those who want to generate and store their own electricity. Can I get a smart...

Based on the tests carried out by the Stiftung Warentest on atmospheric gas boilers, relationships are shown, independent from the design, between the inte... P Loose 被引量: 0发表: 1989年 Comparison between atmospheric pollutants emitted by a fire-tubular boiler fueled by natural gas and fuel...
(phase change), and sub-cooling (liquid). The specific heat has a sharp peak around 200K, which makes the cooling load uneven along the NG flow. In order to achieve a highthermodynamic efficiency, it is crucial to minimize theentropy generationdue to the temperature difference between the ...
