Abstract A flare has a cylindrical body composed of a solid combustible flare composition. One of the end walls of the body is covered with a non-combustible and heat-resistant covering and the side wall of the body is encompassed with a non-combustible and highly heat-resistant wire netting along its entire length. The netting ends substantially flush with the other end wall of the body. Ignition of the flare composition is started at this other end wall. The wire netting prevents direct access of combustion flames to the side wall of the body thereby impeding premature burning at localized areas of the side wall. It also provides a multitude of passages for the flow of fresh combustion air to the burning composition so that the same is gradually and uniformly consumed whereby the luminous efficiency of the flare is markedly increased.
