3) 当锅炉额定蒸发量大于等于6t/h时应除氧，额定蒸发量小于6t/h的锅炉如发现局部腐蚀时，给水应采取除氧措施，对 于供汽轮机用汽的锅炉给水含氧量应小于等于0.05mg/L。
4) 如测定溶解固形物有困难时，可采用测定电导率或氯离子(C1-)的方法来间接控制，但溶解固形物与电导率或与氯离 子(Cl-)的比值关系应根据试验确定。并应定期复试和修正此比值关系。
Industrial boiler water softener equipment introduction - the air conditioning equipment - shenyang demineralized water equipment - shenyang reusing the editor - shenyang industrial water softener
Demineralized water equipment is also called demineralized water device, soft, soft, soft water machine equipment, water softener its main use: salt, electronic or softening, filtration separation, boiler softening, industrial equipment, food and softening softening equipment, household water softening, etc. The main purpose is to let the water resin absorption of calcium, the main components of the scale (form), reduce the source water hardness, and can be used 偱 ring.
Scope of application: used in steam boiler, hot water boiler, switches, ChenFa condenser, air conditioning, direct-fired machine system supplies water softening. Also can be used in hotels, restaurants, office buildings and apartment of life such as water treatment, food, beverage, wine, laundry, printing and dyeing, chemical, hospital etc demineralized water treatment

Table 1 (out)
1 mmol/L) hardness of basic unit for c (1/2Ca2 + 1 / +), 2Mg2.
2) mmo1 alkalinity of basic unit for the L/c (OH -, 1/3, 2CO2 - HC03 -).
High quality requirements for steam, and not without superheater of boiler, use the unit boiler and pressure vessel in the local SSBB to agree, alkalinity index of the upper limit value can relax appropriately.
3) when the boiler rated evaporation is equal to the author shall be rated less oxygen evaporation, the author found the/h boiler corrosion, local water supply should take measures to oxygen, the steam turbine in for the boiler should be less oxygen is 0.05 mg/L.
4) such as dissolved solids have difficulty, can use determination of chloride ion or conductivity (C1) method to indirect control, but dissolved solids and electric conductivity and chlorine or from child (Cl - the ratio of the relationship should be based on tests. And should be regularly retest and correction ratio of the relationship.
5) all welding structure boiler can control the basicity relative.
6) only fuel and gas boiler
2 and rated evaporation 2t/h, less than or equal to and steam pressure rated less than or equal to 1.0 MPa of boiler and steam boiler (such as soda and for steam, water quality, no special requirements) and can use the pot dosing process. But must for boiler scale and corrosion and quality supervision, conscientiously dosing and drainage and cleaning work, the water quality in table 2 should comply with the regulations.
