Because the operation time of low temperature is long, the interior fire tube of boiler produces a large amount of and takes the acid comdenstion water, produces the corruption to the fire tube of boiler to the life of greatly reduced boiler. The normal service life of one boiler is more than or equal to 8 years, and the long-term low-temperature start operation time is long, so that a large amount of acidic condensate water is generated to corrode the boiler, and the service life of the existing boiler is less than 50% of the normal service life.

2. The existing natural gas hot water boiler, alcohol-based fuel or electric water boiler can not reach rated load. Under normal conditions, the normal load of the 0.7MW normal-pressure hot water boiler can meet the requirement of heating of 6000 square meters, and in practice, the 0.7MW normal-pressure hot water boiler can not achieve the heating of 3000 square meters, and the main reason is that the low-temperature starting time is too long, so that the starting power can not meet the requirement.

3. The existing normal pressure hot water boiler has too large reactive power loss due to long low temperature starting time, so that a part of the heat power of the boiler is useless in the time period when the boiler operates at low temperature and does not meet the requirement of heating temperature, thereby greatly reducing the heat efficiency of the boiler. According to actual detection, 75% of useful work done by the boiler cannot be achieved, and the thermal power of the boiler is low.

4. The methanol fuel normal pressure hot water boiler has high exhaust gas temperature in the running process and much heat in the exhaust gas, thereby not only causing the waste of heat energy and reducing the heat efficiency of the boiler, but also being easy to pollute the environment.
