This is our first collaboration with fast what is hot water supply boiler, professional and caring service fast boiler's impressed us. From pre-sales advice to after-sales guidance, every step is very careful and thoughtful. They provide hot water boiler performance is also very good, and effectively improve the level of our heating units. --customer feedback
Boiler flue gas condenser can effectively reduce production costs, reduce exhaust gas temperature of the what is hot water supply boiler, the boiler thermal efficiency. To run the boiler in line with the national energy saving standards. Energy conservation is the national "Eleventh Five-Year Plan" key and ensure transformation of economic development is to implement the scientific concept of development and to ensure that an important indicator of fast economic development, energy-hungry as special equipment, but also environmental pollution important source of special equipment to strengthen the task of energy saving long way to go. "National Economic and Social Development 10th Five-Year Plan" to establish a unit of GDP total energy consumption by 20% to 10% reduction binding targets economic and social development of the total discharge of major pollutants. With its industrial production is the "heart" of the energy consumption of the boiler is large. High-performance special equipment mainly refers to the boiler, a pressure vessel heat exchanger equipment. Gas-fired steam boiler 'boiler energy saving technical supervision and management regulations "(hereinafter referred to as" Regulations ") on December 1, 2010 came into force. And the boiler flue gas temperature can not be raised above 170 ℃, the thermal energy efficiency of the gas boiler 88% or more, does not reach the efficiency metrics for the use of the boiler can not be registered. In a conventional boiler, fuel combustion in the boiler, the exhaust gas temperature is relatively high, the water vapor in the flue gas is still in a gaseous state, it will take away a lot of heat. In all types of fossil fuels, the highest quality of natural gas the hydrogen content of the hydrogen percentage of about 20% to 25%, and therefore, the exhaust contains large amounts of water vapor, it is estimated that one square meter of combustion steam to natural gas produced heat away paper as 4000KJ, about 10% of its gross calorific value. Flue gas condensation heat recovery unit, with a lower temperature of the water or air cooling the flue gas, the flue gas temperature is reduced to achieve close heat transfer surface area, condensation of water vapor in the flue gas, the sensible heat of flue gas while achieving release of latent heat of condensation and water vapor release, while water or air absorbs heat in the heat exchanger is heated to achieve heat recovery, improve the thermal efficiency of the boiler. Boiler thermal efficiency increase: 1NM3 natural gas combustion flue gas production theory is about 10.3NM3 (about 12.5KG). Excess air factor of 1.3, for example, flue gas produced 14NM3 (about 16.6KG). Take decreased flue gas temperature of 200 degrees Celsius and 70 degrees Celsius, physically sensible heat released about 1600KJ, taking water vapor condensation rate of 50%, releasing latent heat of vaporization of about 1850KJ, total heat 3450KJ, about 10% of the net calorific gas, if the taken 80 % flue gas into the heat recovery, energy efficiency can be improved more than 8%, natural gas fuel savings of nearly 10%. separate arrangement, the installation forms, flexible and reliable. Spiral finned tube as a hot surface, heat transfer efficiency, sufficient heating surface, the flue gas side of the system small negative force, meet the general requirements of the burner.
In addition, another company for industrial steam boilers requirement is that, if there are problems to be easy to check and repair. At present, the market is relatively hot in several industrial steam boilers brand has the advantages of easy maintenance, such as fast boiler it, in all vulnerable parts of the boiler addition of manholes and hand holes, to facilitate post technical maintenance personnel, also enterprises can reduce maintenance costs for the boiler.
How fuel (gas) what is hot water supply boiler stack height standards should be implemented as specified? A: GB13271-91 "boiler air pollutant emission standards" in the stack height is not specified for the fuel (gas) boiler. In order to install the units at the time of fuel (gas) boiler to protect the people around undisturbed, you can refer to the boiler emission standards on fuel (gas) boiler stack height is currently being revised in:
