Energy-saving and environment-friendly gas condensing module heating unit

Abstract

The invention relates to heating equipment, in particular to an energy-saving and environment-friendly fuel gas condensation module heating unit. The heating unit comprises a fuel gas condensation boiler, wherein the fuel gas condensation boiler comprises a first fuel gas condensation boiler part, a second fuel gas condensation boiler part and a third fuel gas condensation boiler part; an intelligent group controller is arranged on the first fuel gas condensation boiler part; and an intelligent controller a and an intelligent controller b are respectively arranged on the second fuel gas condensation boiler part and the third fuel gas condensation boiler part, and are connected with the intelligent group controller. The heating unit has the benefits that a variable frequency fan conveys preheated combustion-supporting air, so that favorable conditions are provided for fully-premixed complete combustion; a bevel scavenging air nozzle is adopted, and a brute force air curtain is formed on the circular surface of a combustor, so that the combustor is protected, and micro flame combustion on the surface of the combustor can be complete, stable, reliable and energy-saving; and with the adoption of a control mode combing a boiler module automatic control system with multiple boiler module group control systems, a scientific, environment-friendly and energy-saving running mode in which equipment is fit with practical heating load requirements is realized.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating unit. Background technique [0002] In the prior art, the heating boiler in the heating unit is a condensing boiler, that is, the design is made on the condensation and energy saving of the flue area of ​​the gas boiler; or a special design is made on the boiler body, but the material is generally stainless steel, and the combustion part is blast combustion. Machine, the heating method is long flame type, segmented type, which is not conducive to load adjustment, and the boiler body is in low temperature operation state for a long time. Gas-fired boilers work under low load for a long time, resulting in low boiler efficiency, insufficient combustion, substandard emissions, and condensed water on the boiler body, which shortens the life of the equipment due to condensation corrosion. The thermal efficiency of traditional boilers can only reach the design standard when the actual load...

[0002] In the prior art, the heating boiler in the heating unit is a condensing boiler, that is, the design is made on the condensation and energy saving of the flue area of ​​the gas boiler; or a special design is made on the boiler body, but the material is generally stainless steel, and the combustion part is blast combustion. machine, the heating method is long flame type, segmented type, which is not conducive to load adjustment, and the boiler body is in low temperature operation state for a long time

The gas-fired boiler works under low load for a long time, resulting in low boiler efficiency, insufficient combustion, substandard emissions, and condensed water on the boiler body, which shortens the service life of the equipment due to condensation corrosion

The thermal efficiency of traditional boilers can only reach the design standard when the actual load basically matches the rated power of the equipment; in fact, the equipment operates at 60% or below load for more than 80% of the time in the entire heating season, and the output thermal efficiency is extremely low. The occurrence of condensation will cause severe condensation and corrosion of the furnace body, and poor combustion conditions will cause the exhaust gas to fail to meet the standard, resulting in serious environmental pollution
