hot water boiler to foreign markets
1, natural gas boiler degree of automation is very high, generally need only a simple user interface control, to complete the startup, shutdown and adjustable parameters, labor cost is very low.
2, flue gas condensation recovery boiler is provided with a tail, by the secondary recovery of the high temperature flue gas, so that the thermal efficiency is further enhanced when the gas boiler flue gas temperature is reduced to below 80 ℃, its efficiency can be increased to 108 %the above.
3, the internal gas boiler larger heat transfer area and wings tubes finned tubes, light pipes in general, the heat transfer area can be increased 5-fold compared to the overall area of the boiler is directly reduced about 40%. For less demanding to build a boiler room, boiler room can save capital costs.
4, due to the natural gas boiler using clean energy sources, will not produce the combustion process in the furnace soot and dust, the degree of smoke pollution emissions is also low, truly clean and green, can significantly improve the use of units on-site environment, regional environmental requirements to be high, and has a clear advantage.
5, the choice of materials, natural gas boilers do a great degree of change, anti-corrosion treatment, pipe insulation, packaging materials ...... These measures have made the boiler has stronger corrosion resistance, life will naturally run longer than other types of boilers.
SZS type fuel gas boiler flue gas temperature is lower flue gas loss is smaller SZS type fuel boiler thermal efficiency related to many factors, one of which is the exhaust gas temperature of the boiler, based on past experience, type of fuel gas boiler SZS the lower exhaust gas temperature, exhaust loss of the smaller, the higher its thermal efficiency. But in the design to reduce exhaust gas temperature, then we must increase the tail heating surface SZS type of fuel gas-fired boiler, which requires increased investment and metal consumption. And if the exhaust gas temperature is too low, reach the dew point temperature of flue gas, the sulfur dioxide in the flue gas condenses on the wall surface of the air preheater, a low-temperature corrosion. Especially when SZS type fuel gas-fired boiler to burn more fuel sulfur content, this low-temperature corrosion can appear more intense. Low exhaust gas temperature should be determined by a technical and economic comparison, the fuel gas for the boiler type SZS large capacity, the exhaust gas temperature is generally rated at between 110 ℃ ~ 160 ℃ it.
Directly under the Central Government Offices Administration (referred to as the straight Authority) is the CPC Central Committee and subordinate units, are responsible for the CPC Central Committee and services for the organs and services, an important function of serving the people. Central Government institutions funds, finance, public service vehicles, the state-owned assets and real estate management, service management is responsible for the specified life of the party and state leaders as well as services related objects.
Effects of changes in vapor pressure heating boiler steam temperature change on the stove vapor pressure of the steam temperature: Usually when the steam pressure is increased, the superheated steam to rise. This is because when the vapor pressure increases with an increasing saturation temperature, from water into steam need to consume more calories in the case of the fuel constant, the instantaneous evaporation of the boiler to reduce, i.e. the superheater by reducing the amount of steam, the steam is increased relative to heat absorption, resulting in superheated steam temperature.
