Environment-friendly energy-saving boiler

Abstract

The invention relates to an environment-friendly energy-saving boiler, comprising a boiler body, auxiliary equipment, a safety device and a water treatment device. The environment-friendly energy-saving boiler is characterized in that the water treatment device is connected with a solar water heating device through a water intake pipeline; the water discharging pipeline of the solar water heating device is connected with the water-filling pump of the boiler and then is connected with the boiler through a water-filling pipeline; the lower part of the water discharging pipeline of the solar water heating device is connected with a water storage tank; the water storage tank is connected with the water-filling pump of the boiler and then is connected with the boiler body through the water-filling pipeline; the auxiliary equipment is connected with the safety device; and a hearth, a boiler barrel, a combustor, a water-cooled wall overheating device, an economizer, an air pre-heater, a framework and a furnace wall in the boiler are connected in sequence.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to an environment-friendly and energy-saving boiler that can use both solar energy and fossil fuel energy. Background technique [0002] Now in our life, boilers have been applied to more and more fields. At present, most common boilers obtain heat by burning coal, oil, gas, etc. These methods of obtaining heat energy generally have the following disadvantages : The burning cost is high, the air pollution is big, not only not environmentally friendly but also easy to cause harm to people. With the development of society, some new energy sources such as solar energy and wind energy have also been developed and utilized. These new energy sources have the advantages of no pollution and low cost of use. And solar energy has the advantages of large energy and easy collection, which can be converted into heat energy, electrical energy, mechanical energy and other energy sources. In toda...

Problems solved by technology

[0002] Now in our life, boilers have been applied to more and more fields. At present, most common boilers obtain heat by burning coal, oil, gas, etc. These methods of obtaining heat energy generally have the following disadvantages : High combustion cost, great air pollution, not only not environmentally friendly but also easy to cause harm to people

[0005] In addition, during the frequent start and stop of the boiler, due to the poor combustion conditions of the furnace sill, the fuel is not easy to burn out, and when the flue gas flow rate is low, it is easy to cause a large amount of unburned combustibles to deposit; the boiler runs for too long at low load , the combustion is unstable, the smoke velocity is low, and the unburned combustibles are easy to deposit on the corrugated plate; the lessons and experience of previous accidents also prove that: the rotor of the air preheater is clogged with dust, air leakage after wear, and the excess air coefficient at the tail of the flue or Oxygen content control is too low, etc. can lead to incomplete combustion of fuel due to lack of oxygen

At present, the rotors of the air preheaters of boilers A and B of the company have different degrees of hidden dangers of air leakage; after 1997, the boilers have not been able to operate at full load due to various reasons, and the flue gas flow rate is low; Tail Excess Air Volume

These have left hidden dangers for the secondary combustion of the air preheater
