Cleaning method of boiler scale in common useScale is one of the most harmful sources of cast iron hot water boiler. Therefore, in order to ensure the safe and economical operation of cast iron hot water boiler, it is necessary to remove boiler scale in time. To give you a brief description of three commonly used and effective boiler scale removal methods: mechanical scale removal method, acid washing scale removal method and alkali cooking scale removal method. 1. alkali cooking scale removal method: alkali cooking scale removal method, its effect is worse than the acid washing scale removal method, but after alkali cooking due to water scale loose, Therefore, the scale which is difficult to remove with hydrochloric acid can also be treated once before pickling. The alkali cooking method is simple to operate, and the side effect is relatively small. The disadvantage is that the cooking time is longer, the medicament consumption is more, and the effect is poor.2. Mechanical scale removal: when the cast iron hot water boiler has loose scale and slag in the furnace, the cast iron hot water boiler is cooled after stopping the furnace, and the furnace water is released. After washing with clean water, the scale can be descaled with flat shovel, steel wire brush and motor tube mill. This method is relatively simple and is often used in small cast iron hot water boilers with simple scaling. However, high labor intensity, poor scale removal effect, easy to damage the boiler body. 3. acid washing scale removal method: most of the acid washing scale removal method is hydrochloric acid or nitric acid to clean. The pickling solution is composed of hydrochloric acid plus corrosion inhibitor or nitric acid plus inhibitor. This kind of pickling solution can not only remove the scale in boiler (when removing nitrate scale, but also need to add it). Hydrofluoric acid), and very little corrosion cast iron hot water boiler. Pickling has the effect of dissolving, peeling and loosening.

Philippines is mainly an agricultural country with a land area of 30 million hectares, 47% of which is agricultural. The total area devoted to agricultural crops is 13 million hectares distributed among food grains, food crops and non-food crops. Among the crops grown, rice, coconut and sugarcane are major contributors to biomass energy resources.

April 15 --16 days, ASME joint review by the American Society of Mechanical Engineers group assignment, our company ASME quality control system and demonstrate products on-site audit. After a strict and rigorous audit, the joint review team leader (AIS) announced: "fast Boiler Co., Ltd.-site audit by ASME recommendation issued: power boilers (S) and pressure vessel (U) Certification and Seal"

According to many ways now people can see inside the szs d type water tube steam boiler to pay attention to when such a situation would be to meet the most different aspects of the people, so that now a better time to analyze it, is itself heated aspects the effect would be to meet people in different ways, and now from the way people see better to take into account when the integrity of the part can be achieved will naturally be different.
