Comparison of thermal efficiency of two drying vacuum boiler dealer heatings: 1, vacuum boiler The water volume is small, the primary water does not participate in the system cycle, the number of start-up times of the burner is more than that of the normal pressure boiler, the combustion heat efficiency of the burner is low, and the thermal efficiency of the vacuum boiler is up to 91% under the premise of stable vacuum degree. The change of vacuum caused by the unstable operation of boiler auxiliary equipment will also reduce the thermal efficiency. The operating cost can not be stable, and the thermal efficiency decreases with the decrease of the service life of vacuum pumping equipment and control components and the increase of failure rate. 2, atmospheric boiler The hot water volume is larger than the vacuum boiler, the primary water does not participate in the system circulation, the burner starts up less times, the burner combustion heat efficiency is high, the hot water boiler thermal efficiency is also 91%, and the thermal efficiency of hot water boiler is stable in operation. There is no effect on the failure rate of so many devices, and the structure is simple and durable.
Hot water drying vacuum boiler dealer heating in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
1, boiler good safety performance. Vacuum hot water boiler operating member remains negative pressure state, even if sudden failure occurs, it will not cause a dangerous situation outwardly explosion.
2, the actual high thermal efficiency. Due to the small heat capacity of the boiler, the heating time is short, low heat losses start-stop; while high-quality insulation materials, heat loss will be reduced to very low, the actual operation of the thermal efficiency is greatly enhanced.
3, long service life. Boiler operation remain closed, heating medium water at the factory once the injection is complete, and is highly processed deoxy, softening, etc., without having to use the latter supplement and does not scale to ensure the long-term normal use of the boiler.
4, very environmentally friendly features. I produced by using a vacuum hot water boiler premix, advanced combustion technologies of FGR greatly reduced emissions of nitrogen oxides (NOx) and other harmful substances, using a condenser with the flue gas economizer heat fully utilized, only reduce exhaust gas temperature, NOx emissions have also been reduced, very environmentally friendly features.
Several vacuum pressure gas discharge energy drying vacuum boiler dealer heating substantially in China reason to catch coal gas work, the application of vacuum gas boiler, a very large reduction of fouling contamination, together with nitrogen oxides and other health effects of gas He won the curb. Energy labeling is an important measure vacuum gas boiler, well that is that we begin to study the energy consumption of gas under pressure vacuum boiler several reasons. After investigation, the relevant departments of the gas boiler vacuum heat loss is probably produced in these two places included: full combustion flue gas emission values are not as well as heat loss. Emission reduction of heat loss to be recycled at the end of the assembly setter exhaust gas heat recovery boiler in vacuo or more application functions leading condensing boiler. Value is not over the full combustion substandard summary: Select the common gas ejector type vacuum boiler burner, leading to the air-fuel ratio can be adjusted to maneuver. A majority of the gas is chosen vacuum boiler burner exhaust mechanical strength, air-fuel ratio over the reasons leading to the following aspects: air-fuel ratio does not contain over about two cases: when the airflow in excess, there will be over-full cold heat is conducted to increase the operating costs incurred by the gas boiler vacuum, reduced energy consumption vacuum gas boiler; when the airflow is not enough, there will be insufficient to ignite the situation, resulting in reduced energy consumption of the gas boiler vacuum.Free Chat
