The problem that directly affects the service life of the boiler is the corrosion and scaling problem. The circulating water is repeatedly heated, and the suspended solids, colloidal mixture and various dissolved impurities contained in the water, especially the bacteria, algae and microorganisms contained in the water are attached. The heat exchanger and the inner wall of the pipeline directly cause corrosion of the boiler heat exchanger and its pipeline, which eventually causes leakage and seriously affects the service life of the boiler. The fouling will increase the consumption of natural gas, increase the cost, increase the sound of the pump operation, lower the temperature of the indoor heating, lower the temperature of the bath and kitchen water, and the coldness of the kitchen. The following two methods are effective to deal with the decay of the fireplace. Fouling problem.
Regularly clean and maintain the fireplace:
Cleaning is our so-called "pickling", which is used more in the boiler and central air-conditioning industry. As the name implies, the main component of the solution is acid (manufactured by dilution with hydrochloric acid). No matter how the cleaning solution is named, its main component must be "acid", because only the acid solution can dissolve the scale. By cleaning, the efficiency of heat exchange in the wall-hung boiler can be improved, and the gas consumption can be reduced. Effectively reduce the load of the main components such as pumps and heat exchangers, and prolong the service life, but it requires professional and construction qualified personnel to operate the construction. Otherwise, if the cleaning is improper, it will cause damage to the heat exchanger and its pipeline (acid corrosion). , causing a leak.
Regularly add scale inhibitors and preservatives to circulating water:
The National Standard for Gas-fired Heating Water Heaters, which was implemented on July 1, 2011, recommends that users use scale reducing agents in circulating water when using gas wall-hung boilers - we are commonly known as scale inhibitors. Scale inhibitors - chemicals that prevent the formation of scale on metal surfaces. It has been proved by repeated experiments that it is necessary to frequently replenish and replace the scale inhibitor, and the agent will also aggravate the corrosion of the metal surface and cause serious pollution to the living environment.
