Economic and efficient steam boiler with long service life

Introduction price of condensing boiler boiler economic benefits to improve the thermal efficiency of the boiler fuel gas economic and efficient steam boiler with long service life of the price, at the same time, can greatly save fuel, thus greatly reducing operating costs. 1 ton of fuel gas steam boiler Wan, for example, ordinary boiler natural gas consumption is 75.9Nm3 / h (natural gas low calorific value 8500kcal / Nm3), condensing boiler natural gas consumption is 66Nm3 / h, if the boiler operation every day 24 hours, using a condensing boiler can save 237.6Nm3 natural gas per day of natural gas price 2.9 yuan / Nm3 daily basis to save operating costs 689.04 yuan, the annual operating cost would save 248,000 (annual working time of 360 days calculated), even more than boiler cost is higher.

The maintenance methods of oil-fired boilers when they are not used for a long time are: dry method and wet method. When the boiler is shut down for more than one month, dry maintenance method shall be adopted. (1) Wet maintenance method: after the boiler is shut down, the water from the furnace shall be discharged, and the method of wet maintenance shall be adopted for a period of less than one month. Thoroughly remove the internal dirt, rinse clean, reinject the treated water to the full, heat the furnace water to 100 ℃, let the gas from the water drain out of the furnace, and then close all valves, and do not use the moisturizing method in cold climates. The boiler is damaged by ice-free boiler water. (2) dry maintenance method: after the boiler stops the furnace, the boiler puts away the boiler water, removes the internal dirt thoroughly, rinses it clean, and dries it in the hearth with slight fire. Dry (pay attention not to fire), then put a 10 / 30 mm diameter lump of quicklime into a tray and place it in a pot tube without contact with metal. The weight of quicklime is calculated in terms of the volume of the drum at 8 kg per cubic metre. Then close all manhole, hand-hole pipe valves, check every three months, replace quicklime if it is broken, and remove quicklime and tray when the boiler is re-in operation.

It provides fast side of boiler equipment, installation and commissioning after all normal, we immediately put into use, the hotel did not delay the normal heating. Meanwhile boiler capacity, energy efficient, fully able to meet the needs of heating and bathing water in our hotel rooms. --customer feedback

Combustion gas, which has several economic and efficient steam boiler with long service life 1, flameless combustion: the air which has been uniformly mixed with the fuel gas prior to combustion gas required, the excess air ratio is equal to a coefficient of excess air for complete combustion of the fuel, not required in the combustion process from the surrounding oxygen in the air to obtain, after the combustion gas and air mixture reaches the combustion zone can be completed in an instant. 2, the diffusion combustion: gas heating boiler fuel gas and air interdiffusion nozzle openings, and combustion. Shao Shao stability advantages, the structure of appliance is simple, but the flame is longer, easy to produce incomplete combustion and carbonization of the heated area. 3, premixed combustion: gas heating boiler burner usually used such combustion, a portion of the pre-combustion air is mixed in advance with the gas (primary air excess coefficient between 0.2-0.8), followed by combustion. The advantage is clear combustion flame, combustion strengthened, high thermal efficiency, but the unstable combustion, the primary control of high combustible component and air requirements.
