FIELD: chemistry. SUBSTANCE: invention relates to chemistry, particularly to coke chemistry and enables to put into operation the main coke furnace battery when building new coke chemical plants when it is impossible to heat the first (main) battery with coke gas. The method involves feeding heating gas into coke furnace chambers, heating and switching to heating on a constant scheme until intrinsic reverse coke gas is obtained. The battery has bottom or lateral supply of heating gas, the heating gas used being re-gasified liquefied propane-butane gas. Furnace burners are fitted with a screen and are mounted in the temporary inner hearth of the coke furnace with on the machine and coke side of the battery. Air is fed into the hearths through movable screens mounted on hearth windows which are made on the front of the temporary inner hearths or in pre-mounted doors of the coke furnaces. When switching to heating on a constant scheme, upon achieving temperature of guaranteed ignition of the propane-butane gas in all vertical flues, propane-butane gas is fed into a permanent coke gas distributing pipe which is temporarily shutoff from the reverse coke gas supply gas pipe through a pre-installed nozzle with a slide valve, said propane-butane gas being mixed with air fed from a bottom tunnel into units for feeding heating gas into each vertical flue or gas-feed channel. EFFECT: invention reduces consumption of heating gas, provides uniform heating of the refractory masonry of coke furnace batteries with a limited choice of heat carriers without using external hearths and with the possibility of mounting coke furnace doors before heating begins. 1 tbl, 7 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 509 795 (13) C1 (51) МПК C10B 17/00 C10B 21/08 C10B 21/22 (2006.01) (2006.01) (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2012131478/05, 24.07.2012 (24) Дата начала отсчета срока действия патента: 24.07.2012 (73 ...

Coke oven battery preheating - by passing rich gas into branched piping to heat aperture in oven door

METHOD OF KEEPING HOT AN INOPERATIVE REGENERATOR DURING REPAIR IN A COKE-OVEN BATTERY

"A method of keeping hot an inoperative regenerator during repair in a coke-oven battery" ABSTRACT OF THE DISCLOSURE A regenerator in a coke-oven battery which is inoperative during a repair is kept hot in order to prevent the formation of cracks in its structure due to thermal contraction. This is achieved in a simple, effective and cheap way by supplying hot waste gas to the inoperative regenerator from a location upstream (in the waste gas flow direction) of the checker work of one or more operating regenerators through added by-pass conduits during the repair. The temperature of the regenerator can be monitored and controlled by adjustment of the waste gas supply.

Start-up procedure for a pitch coke oven

In order to avoid premature decomposition reactions of a pitch coke oven, largely iron-free coking material such as, for example, coal is coked in a newly erected oven chamber before coking of pitch, until the chamber walls have been largely graphitised, and it is only after this that pitch coking is carried out, for which the pitch is coking from the chamber bottom with a rising pitch level, in order to avoid supercooling which promotes CO decomposition reactions.

Starting procedure for internal combustion vessels

A vertical vessel, having a low bed of broken material, having included combustible material, is initially ignited by a plurality of ignitors spaced over the surface of the bed, by adding fresh, broken material onto the bed to buildup the bed to its operating depth and then passing a combustible mixture of gas upwardly through the material, at a rate to prevent back-firing of the gas, while air and recycled gas is passed through the bed to thereby heat the material and commence the desired laterally uniform combustion in the bed. The procedure permits precise control of the air and gaseous fuel mixtures and material rates, and permits the use of the process equipment designed for continuous operation of the vessel.

Apparatus for heating up a chamber of a coking battery

After replacement of the walls of one chamber of a coking battery this one chamber is heated up by withdrawing relatively hot air from another still-hot chamber of the coking battery and injecting it into the cold chamber. This is done by means of a conduit extending between the two chambers and provided with an internal nozzle that conducts the hot gas from the hot chamber to the cool chamber by jet-pump action. This hot gas is mixed with relatively cool air so as slowly to heat the cool chamber up.
