Embodiment Construction
[0019] Determine the formula (mass percentage) of the cleaning and maintenance agent according to the individual characteristics of each boiler (body structure, pressure, temperature, scale type and amount, length of shutdown time): surfactant 5-20%, penetrant 5-8%, stripping agent 5-15%, dispersant 5-20%, surface passivation agent 5-10%, and the balance is water. For units with high temperature and high pressure and low fouling amount, the lower limit can be taken for surfactants, penetrants, stripping agents, dispersants, and surface passivators; for systems with high fouling amounts, surfactants, penetrants , stripping agent, dispersant, and surface passivation agent can take the upper limit, once several cycles of cleaning are carried out, the surfactant, penetrating agent, stripping agent, and dispersant in the medicament can take the lower limit.
[0020] The steps that the present invention implements are:
[0021] 1. Add the cleaning and maintenance agent into the dru...
