    在燃煤锅炉改造过程中,首先要选择或设计合适的燃气燃烧器。常见的燃气燃烧器按照空气供给方式可以分为引射式燃烧器、鼓风式燃烧器和自燃引风式燃烧器三类。

    In the process of retrofitting coal-fired boilers, the first choice is to design or design suitable gas burners. The common gas burners can be divided into three categories: ejector burner, blast burner and self ignition air induction burner according to the air supply mode.

    1)燃气燃烧器的安全程度,也就是要求降低气体不完全燃烧热损坏。燃烧的完全度主要与燃气和空气混合均匀程及空气是否充足有关。

    1) the safety degree of gas burners, that is, to reduce the heat damage caused by incomplete combustion of gas. The completeness of combustion is mainly related to the mixing of gas and air and the adequacy of air.

    一般在空气量充足、混合良好的情况下,使气体不完全燃烧损失为零并不困难。当燃用高热值燃气时,气体不完全燃烧损坏不应超过0.5%;燃用低热值气体时,气体不完全燃烧损坏不应超过1.5%。

    Generally, it is not difficult to make the incomplete combustion loss of gas zero when the air volume is sufficient and the mixture is good. When burning high calorific value gas, the damage caused by incomplete combustion of gas should not exceed 0.5%. When burning low calorific value gas, the damage of incomplete combustion of gas should not exceed 1.5%.

    2)降低烟气中的过剩空气系数是降低排烟损坏有效措施。排烟中的过剩空气量与烟气通道漏入的空气量之和。

    2) reducing the excess air coefficient in flue gas is an effective measure to reduce smoke damage. The sum of the excess air in the exhaust gas and the amount of air leaked into the flue gas passageway.

    对微正压运行的锅炉,烟气通道漏入的空气为零,此时主要过剩空气量取决于燃烧时的过剩空气量取决于燃烧时的过剩空气量,实际上在任何情况下,降低燃烧时的过剩空气量,对提高锅炉的热效率是有好处的。

    For the boiler operating in the micro positive pressure, the air leakage in the flue gas channel is zero, and the excess air amount depends on the excess air in the combustion, in fact, in any case, it is beneficial to reduce the excess air in the combustion and to improve the thermal efficiency of the boiler.
