Fuel oil condensing boiler reverse-balancing heat efficient measuring method

Abstract

A method for measuring anti-balance heat efficiency of boiler in fuel oil condensing type includes selecting datum and reference temperature; analysing fuel composition; measuring fuel heating value, air pressure and air relative humidity, volume content of composition in smoke, temperature of smoke fuel, consumption and condensed water in smoke; selecting method for calculating heat efficiency and utilizing model to operate out boiler heat efficiency.

Description

Technical field [0001] The invention relates to the field of boilers of thermal energy engineering, in particular to a method for measuring the counterbalance thermal efficiency of an oil-fired condensing boiler. Background technique [0002] Conventional boiler thermal efficiency measurement and calculation models generally use the thermal calculation model of the former Soviet Union. This conventional model is based on the thermal efficiency analysis method of fuel low calorific value, because the exhaust gas temperature of conventional boilers (including power station boilers and industrial boilers) is generally higher than 170℃, and the steam in the wet flue gas discharged from the boiler is in gaseous state. It is discharged directly without condensation, and the latent heat of vaporization of water vapor is not used. At this time, the calculation model is suitable for the thermal performance test procedures of conventional boilers. [0003] For oil (or gas) condensing boile...

Problems solved by technology

At present, a large number of condensing boilers from abroad have begun to pour into the domestic market, and some domestic companies have also begun to design and develop condensing boilers, but there is currently a lack of a calculation model and calculation model for calculating and testing the thermal performance (thermal efficiency) of fuel (or gas) condensing boilers. Test method, the significance of the present invention is to fill this technical gap, and based on the present invention, a new type of high-efficiency and energy-saving boiler thermal performance test specification will be established to calculate, test, evaluate, and monitor the thermal performance of condensing boilers. Greatly promote the progress of my country's fuel energy conservation work, and urge domestic enterprises to implement new energy-saving technologies to increase the energy-saving competitiveness of domestic products
