Gas boiler cleaning

Boilers, after prolonged operation, inevitably develop scale and corrosion issues. The primary cause of scale formation in boilers is the presence of hardness components in the feed water. As the water undergoes continuous evaporation and concentration at high temperatures and pressures, a series of physical and chemical reactions occur inside the boiler, ultimately forming hard, dense scale on the heating surfaces. This reduces heat exchange efficiency and, due to under-scale corrosion, can lead to a decrease in the boiler's water-cooled wall's heat absorption, increasing the outlet temperature of the boiler furnace, thereby increasing boiler losses. Additionally, the scaling inside the water-cooled walls can reduce heat transfer efficiency, potentially causing an increase in wall temperature and leading to pipe bursts in the water-cooled walls, affecting the safe operation of the boiler. Scale is the "root of all evils" in boilers and is a major cause of boiler accidents. Its main hazards include: wasting a large amount of fuel. Since the thermal conductivity of scale is only a fraction of that of steel, the formation of scale on the heating surfaces hinders heat transfer. To maintain a certain output of the boiler, the fire-side temperature must be increased, leading to heat loss through radiation and exhaust gas. Currently, high-efficiency, environmentally friendly, and non-corrosive cleaning agents can be used to clean gas boilers, revealing the original color of the metal in the tubes and reducing the impact of scaling and biological algae sludge. They also have a剥离 effect on iron oxide and sub-oxide, which can extend the service life of gas boilers, reduce energy consumption, and improve productivity. [2]

Heze Boiler FactoryThe YY(Q)W type gas heat-conducting oil furnace produced by our limited company is a new type of special boiler with low pressure and high-temperature operating characteristics. Its heating temperature can reach up to 340℃ in the liquid phase or 400℃ in the vapor phase. It can serve as a high-temperature heat source below 350℃, widely used in various industries that require high-temperature heating or drying. It features high temperature, low pressure, precise temperature control, and high thermal energy utilization. An optional steam generator can also be added to produce saturated steam below 1.3MPa for user convenience. Organic heat carriers can be used for heating in various production scenarios where uniform and stable heating is required, and direct flame heating is not permitted, with heating temperatures ranging from 150℃ to 380℃.。This gas-fired organic heat carrier boiler typically uses oil or gas as fuel, with thermal oil as the medium. It employs a thermal oil circulation pump to force the medium into a liquid-phase circulation, transferring heat to the heating equipment and then returning to the boiler for reheating. It boasts high working temperatures at low pressure and can perform high-precision control of the medium's operation. The system has a high thermal utilization rate, is easy to operate and maintain, and is an ideal, safe, efficient, and energy-saving heating equipment of choice.。
