When we mediate for the boiler incinerator, we should not speculate spontaneously. It needs professional technical knowledge and professional technical staff to mediate. It can make the boiler incinerator good things and the application life is longer. Because the parameters of the machine are extremely serious. If we don't understand the machine very well, we should not speculate on it In case of delaying the service life of the machine.
The mediation of boiler incinerator requires not only rich practical knowledge, but also many years of practical experience. Let's focus on the following:
① take the flame inspection supervision window as one of the main supervision pictures. The flame in the confrontation furnace is stable, golden yellow in light, not inclined, not attached to the wall, and full of meaningful flame.
② when the oxygen content at the outlet of the air preheater is within the limit of 4% - 6%, and the dark red and long flame or even black smoke from the chimney is found, the air baffle of the boiler shall be adjusted in real time, the reasonable air distribution shall be installed, the joint venture of the air volume and powder quantity shall be confronted, and the combustion shall be conducted in the furnace.
③ the coal level of the coal bunker shall be supervised from time to time to avoid the coal break of the pulverizer composed of the empty coal bunker.
④ when the boiler burning is unstable, the boiler soot blowing and the start and stop of pulverizing system shall be avoided.
⑤ observe the flame environment on site, pay attention to the air leakage in the furnace, and the fire hole and coke hole shall be closed precisely.
⑥ the operating staff shall understand and control the characteristics of the incoming coal in real time, and make sure that there are countless changes in the quality of coal in their mind, and install reasonable burning.
⑦ observe and explain the boiler fly ash and bottom ash on time, conduct burning mediation in real time, and confront the economic operation of the boiler.
In the direct fired pulverizing system, the operation load of the boiler is indirectly related to the force of the pulverizer, which makes the whole pulverizing system often not operate under economic conditions. Because the power of the pulverizing system is the coal quantity entering the furnace, the alteration of the air permeability of the system affects the joint share of the primary and secondary air, and then affects the stability of the operation of the boiler and the combustion conditions in the furnace. The air volume and coal quantity of the pulverizing system are changed with the operation load of the boiler, and the concentration of the gas powder in the system is changed again and again. According to these characteristics, various influencing factors are summed up and considered, and the burning mediation of the actual failure is held, so as to ensure the safe, stable and economic operation of the unit.
The mediation request of the boiler incinerator is extremely high. Even the old technical staff who have experienced for many years can't help but treat every detail with dignity.
