Operating Cost:Let's face it, some of the claims being made about efficiency would make a seasoned politician blush. Unlike a car, the "gas mileage" of your average boiler will degrade over time due to scale and sludge deposits. Putting aside for a moment that many "high efficiency" horizontal straight tube boiler will also require high cost maintenance, a boiler's operating cost can be boiled down to this simple equation: Fuel burned in a new boiler = cost to operate new boiler. Fuel burned in that same boiler that is scaled will cost X more dollars to operate. A boiler can begin to scale up in a matter of months or even weeks. A scaled boiler can turn X into a big, unpleasant number. Don’t buy a boiler that can’t be solved for X … or you’ll be asking yourself why.Scale:aka “lime” “mud” “sludge” “bane of man’s existence” – occurs when dissolved solids (the "hardness" in water) settle out in a pressure vessel. It’s the familiar process that ends the life of most water heaters – and boilers. Solids like to drop out of suspension and plate onto the hottest heat transfer surfaces, and as they accumulate, the water will absorb less energy and the efficiency will drop from good – to fair – to poor. When this happens, the heating surfaces begin to overheat. If the scale can’t be removed, stay tuned for tube or pressure vessel failure. At this point, many boilers are scrapped because the cost to replace can be cheaper than the cost to repair – although cheap is hardly the word that will come to mind of the person paying for it! This is why the engineers at Rite developed the boiler they did: A boiler that can be easily cleaned, field repaired and more than capable of maintaining its brand new efficiency year after year after year. A boiler designed to last a lifetime.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing horizontal type automatic steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
1, boiler feed water in accordance with standard GB1576-2008 oxygen, reduce the oxygen content.
2, during shutdown, a shutdown while the boiler is in the normal high water level and normal pressure, and then close the inlet valve and the main valve, to prevent intrusion of outside air oven.
3, when the furnace is first started slightly open the main exhaust valve until the pressure reaches 0.1-0.15MPa closing the main valve to eliminate air furnace, and then open the main valve when the air supply to the rated pressure.
First, the furnace exhaust gas temperature. The higher the exhaust gas temperature, the thermal efficiency is low; and vice versa. Second, the fuel is completely burned. If complete combustion of the fuel can not be done, then the boiler thermal efficiency is very low. Third, heat dissipation furnace wall strength. The stronger the boiler furnace wall heat dissipation, the thermal efficiency is low; and vice versa. Fourth, the amount of scale furnace. The more scale, the worse the situation furnace heat, the thermal efficiency could be reduced.
