Изобретение отнсситс к обпасти за- жигани и может найти применение при запуске нагревателей с каталитическими насадками.The invention relates to igniting and can be used when starting heaters with catalytic nozzles.

Ближайшим к изобретению вл етс способ запуска нагр ател с каталитической насадкой путем разогрева последней от постороннего источника и последующей подачи на нее горючего.The closest to the invention is a method of launching a heater with a catalytic packing by heating the latter from an external source and then supplying fuel to it.

На каталитическую массу наливают сверху жидкое горючее и поджигают его. Этот способ опасен, неэффективен и неудобен .Liquid fuel is poured onto the catalytic mass from above and ignited. This method is dangerous, inefficient and inconvenient.

Целью изобретени вл етс повыше ние надежности запуска нагревател с каталитической насадкой.The aim of the invention is to increase the reliability of starting the heater with a catalytic packing.

Указанна цель достигаетс тем, что каталитическую насадку перед разогревом предварительно пропитывают жидким горючим в количестве 0,01-0,04 г/смThis goal is achieved by pre-impregnating the catalytic packing prior to heating with liquid fuel in an amount of 0.01-0.04 g / cm.

В предлагаемом способе запуска наг ревател основной прогрев как массь катализатора , так и элементов подачи на In the proposed method of launching the nagvatel the main heating both the mass of the catalyst and the feed elements to

него горючего (испарител , коллектора, фитил и др.) осуществл етс не за счет тепла постороннего источника, как это имеет место при других способах запуска , а за счет тепла, выдел емс о в каталитической насадке при реакции окислени горючего., которым она была npa/fваритепьно пропитана. При данном спосо бе 3afiycKa достаточно нагреть от посто нного источника тепла незначительный its fuel (evaporator, collector, wick, etc.) is not carried out by the heat of an external source, as is the case with other methods of starting, but due to heat, it is released in the catalytic attachment during the oxidation of the fuel. npa / f is heat impregnated. In this way, it is enough to heat 3afiycKa from a constant heat source a slight

Claims

0 a portion of the catalytic packing to start the oxidation reaction of the fuel. This reaction proceeds with ejection of heat and nocTeneTiHO spreads over the entire mass of the nozzle. At the initial stage of starting the heater, its fuel supply system is cold, and therefore the fuel from it is practically not fed to the accumulator. At this stage of start-up, oxidation of the fuel takes place, with which the catalytic packing is pre-impregnated, and at the same time: heat transfers the entire device and brings it to the operating mode. Numerous tests of half-life effectiveness of this method of launch. So, for example, at an ambient temperature of -4 ° C, after the preliminary impregnation of the fuel nozzle with the fuel, the oxidation reaction started within 30 seconds after switching on the same heater. Invention method for starting the heater with a catalytic attachment by heating OZ. 4 last from an extraneous source and the subsequent supply of fuel to it, differing in the fact that, in order to increase launch reliability, the catalytic nozzle is pre-saturated with liquid fuel in the amount of 0, O1-0, O4 g / cm before being heated, Information sources received into account during the examination 1.
