Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

Fourth, the vacuum hot water boiler price in asia mainly take the form of indirect heating boiler, mutatis mutandis, external heat exchanger and circulating water pump in the overall installation cost can save a large part; also has a fast heating, high efficiency and good heat characteristics, to a large extent for the user to save fuel costs.

What are the advantages slip parameter Henan gas boiler unit? Henan gas boiler and turbine generator and start, while boosting boiler ignition, a low boiler parameters using superheated steam turbine to warm up increases the speed with load. Since the Turbo is warm start parameters steam temperature in the case of changing the vapor pressure and the like. Increases the speed. And a small amount of network and receiving the load, so called sliding start parameters, also called kit or unit is started. Many advantages: (1) start with the machine compared furnace separately, from the start to the unit with a full load, the time required is greatly reduced. Each turbine and boiler start-up time required, Henan gas boiler steam turbine start-up and the time required for the individual. And the time required for the steam turbine startup parameter sliding substantially equal to the time required for a single start, even shorter. (2) Since the parameters of the low initial start Henan gas boiler superheater outlet exhaust steam is used to warm recovered heat increases the speed and working fluid losses and part load, caused by exhaust. (3) warm the pipe warm lower pressure and temperature steam, thermal stress is much smaller than with the higher steam temperatures and pressures warm the pipe warm. (4) started separately, since the initial rise fire, the steam superheater is not cooled, burn-out to prevent overheating, you must limit the amount of fuel entering the gas boiler Henan. And slippery start parameter, starting with a vacuum in the condenser, soon there superheater steam cooling, Stokes speed can be significantly faster. At low pressure, large volume flow in the steam superheater, superheater tubes is not as small as the exhaust flow rate (about 15% to 20% of the rated evaporation), the flow rate variation when thermal image is generated individually activated deviation. (5) Sliding Parameters, Henan gas boiler starts to meet the requirements of the turbine increases the speed of the warm-up, because of the time needed to start a steam turbine is sufficient for the boiler. Adjusting the intensity of combustion boiler can be used (i.e., a control quantity of fuel into the furnace) to control starting conditions. When sliding pressure starting, due to the large volume flow of steam, it is advantageous to improve the water cycle and steam drum wall temperature difference from top to bottom.

How about whether the reasoning vacuum gas boiler vendor specializing in formal professional regular vacuum gas boiler vendor can supply to you have experience, targeted one to one design, the second supply can give you a more professional overall system vacuum gas boiler planning, guaranteed to correspond to top standards in our industry, can have a high cost, to make sure we will not have any pressure on provisioning else, for functionality and safety with respect, it can be done successfully the most authoritative standard.
