The exhaust temperature of low nitrogen condensing boiler is one of the basic parameters of boiler. Choosing lower exhaust temperature can reduce the exhaust loss of boiler and improve the thermal efficiency of boiler. If the boiler exhaust temperature falls to a low enough level, then the superheated water vapor in the flue gas will condense and release the latent heat of vaporization. The energy saving effect of gas low nitrogen boiler is remarkable. Based on the low calorific value of fuel, the thermal efficiency can exceed 98%. The harmful components in the boiler flue gas dissolve in condensed water, effectively reduce emissions and improve emission index.
Gas fired boiler adopts frequency conversion feed water and control technology to ensure the condensation rate of steam in flue gas. The condenser adopts “sulfuric acid resistant low dew point corrosion” steel, greatly improving the service life. This series of steam boilers use programmable logic controller (PLC) adequate reserved ports and building blocks expansion module, can achieve group control, remote monitoring and troubleshooting, to reduce the development of special needs of users repeated investment. Multiple boilers are networked to use, without setting the main console, the number of boilers can be automatically selected and the load of each boiler can be distributed.
The gas low nitrogen boiler uses the warped plate economizer and the condensing heat exchanger, which effectively reduces the smoke exhaust temperature. Gas fired steam boiler adopts frequency conversion continuous feed water control to save 40% electric energy. The boiler condenser in order to prevent the acid corrosion of smoke condensate, the use of SUS304 or ND material steel made of finned tube, compared with the light tube, heat transfer efficiency is more than 2 times higher than the straight tube. The harmful gases in the flue gas are effectively controlled and flow into the neutralization tank with the condensate. Boiler water inlet system manufacturer unified configuration, simple, beautiful, greatly saving installation costs.
The combustor of this series boiler adopts cold spinning shaped corrugated furnace, which ensures full combustion of fuel, helps absorb thermal expansion, provides flexibility, reduces thermal stress and extends boiler service life. It produces turbulence to high temperature flue gas, strengthens heat transfer, increases heating area and improves boiler thermal efficiency. The convective heating surface adopts threaded smoke pipe, which makes the flue gas change from laminar flow to turbulent flow, increases the heat transfer effect, improves the boiler thermal efficiency, saves fuel, and effectively reduces the operation cost. The boiler adopts high thermal resistance fiber cotton and stainless steel outsourcing, beautiful appearance, strong, corrosion resistance, low temperature furnace body surface, good insulation performance, improve thermal efficiency.
Gas low nitrogen boiler condensed water in the front and rear smoke boxes during operation prevents tube plate corrosion and prolongs the service life of the boiler. This type of steam boiler is matched with a high-quality automatic water softener and a dosing pump, which can automatically complete the whole process of water softening, dosing and resin regeneration. The gas steam boiler exhaust port can be equipped with a condensing heat exchanger. The water vapor in the condensed flue gas absorbs the latent heat of condensation, thereby improving the thermal efficiency of the boiler. The condensing steam boiler can be equipped with a unique energy-saving device to improve the thermal efficiency of the boiler, reduce the temperature of the boiler exhaust gas, and achieve the purpose of high efficiency and energy saving.
