Использование предложенной конструкции водородно-кислородного пароперегревателя позволяет обеспечить надежное охлаждение камеры сгорания. Подача низкотемпературного пара на самом теплонапряженном участке внутренней вставки камеры сгорания осуществляется через магистраль подачи низкотемпературного пара, состоящую из четырех отверстий, расположенных под углом 30…60° к охлаждаемой стенке камеры сгорания, что обеспечивает ее интенсивное охлаждение. При этом начальная часть камеры сгорания выполнена с коническим расширением с углом 20…35°, позволяющим обеспечить удаление стенок камеры сгорания на расстояние не менее 3-х расстояний расположения форсунок водорода, что обеспечивает 1,5-2-кратное снижение их теплонапряженности. При этом оси форсунок подачи водорода расположены параллельно оси форсунки подачи кислорода, что обеспечивает более протяженную зону горения и снижение удельных тепловых потоков на стенки внутренней вставки. При этом внутренняя вставка выполнена оребренной с наружной стороны, что позволяет обеспечить ее более интенсивное охлаждение. 1 ил.

Устройство для охлаждения пара

Steam-generation method using waste heat - involves superheating saturated stream generated in both heating stages

The method uses waste heat to generate fresh steam, particularly for driving a turbine. A first heating stage generates lower-temperature steam, the saturated steam (D1) produced by it being superheated in the second to bring it to the desired temperature. The second stage also generates saturated steam (D2). This is combined with that from the first stage into saturated steam (D3) superheated in the second stage. ADVANTAGE - Improved efficiency without additional firing.

Steam generation procedure

At least a portion of the superheated steam in the superheater (3), and the re-superheated steam in the re-superheater (9), are subjected to an indirect exchange of heat, depending upon the size of the load on the steam generator (1). The heat exchange is reversible so that with low loads on the steam generator part of the heat energy of the superheater is yielded to the steam of the re-superheater, and vice versa at high loads.

Arrangement for protection of tubes of a tube bundle in a dust-laden gas flow

The invention relates to an arrangement for protection of tubes of a tube bundle in a dust-laden gas flow, in particular of cooled tubes of a downstream heating surface in the smoke gas flue of a steam boiler. The aim of the invention is to provide, by means of a new constructional solution, a more comprehensive protection with lower expenditure. This is achieved in that, according to the invention, the tube which is not subject to flow is provided with a bend facing the gas flow, the end of the bend is fixed to a fixed point of a plant part, e.g. a support rod, and the tube which is not subject to flow is fixed directly in front of the bend at a fastening point of the tube, while the other part of the tube which is not subject to flow is held via freely movable guide points on the tube. ...

Injection cooler for superheated steam - has separate cooling water and atomising steam bores at specified angle and inserted expansion joint

The nozzle is used for injection cooler with water and steam atomisation for cooling of superheated steam. Cooling water and the atomising steam are ejected together from the nozzle. The quantity of atomising steam is relatively low and the length of the injection cooler is reduced, while ensuring high efficiency of atomising. The nozzle has a number of separate holes (22, 23) for the cooling water and for the atomising steam which meet in pairs at a specified angle. The cooling water channel (18) and the atomising steam channel (17) are formed by two concentric tubes (15, 16) which are welded at their ends together and the inner tube (16) has an expansion joint (21) with a water draining nozzle.

ВОДОРОДНО-КИСЛОРОДНЫЙ ПАРОПЕРЕГРЕВАТЕЛЬ

Предлагаемая полезная модель относится к силовым установкам паротурбинного типа, отличающимися камерой сгорания трубчатого типа, использующей в качестве горючего газообразный водород, а в качестве окислителя газообразный кислород, и предназначена для обеспечения перегрева низкотемпературного водяного пара. Использование предложенной конструкции водородно-кислородного пароперегревателя позволяет обеспечить интенсивное перемешивание высокотемпературного и низкотемпературного потоков водяного пара и низкую неравномерность поля температур в генерируемом паре для конечного потребителя. Для обеспечения более интенсивного смешения низкотемпературного и высокотемпературного пара на выходе из камеры сгорания предусмотрен блок вторичной подачи низкотемпературного пара, который имеет четыре отверстия, расположенные под углом 90° к оси камеры сгорания. В результате смешения и последующего резкого расширения потока происходит его интенсивное перемешивание в камере смешения, что обеспечивает образование равномерного поля температур на входе к потребителю, в частности, перед паровой турбиной. 1 ил.

Компактный пароперегреватель для банной печи

Устройство относится к области тепловой техники, а именно к устройствам получения пара и может быть использовано при оборудовании бани мобильного либо стационарного типа с целью получения мелкодисперсного, т.н. «сухого» перегретого пара и создания комфортной для дыхания банной атмосферы. Компактный пароперегреватель для банной печи содержит корпус с входным и выходным патрубками дымохода, расположенный внутри корпуса теплообменник, в нижней части корпуса пароперегревателя расположена полость коллектора для влажного пара, соединённая через паропровод с теплообменником, теплообменник выполнен в виде трубки с развитой внешней поверхностью теплообмена. Теплообменник может быть выполнен гофрированным. При этом процесс парообразования и пароперегревания разбивается на две последовательные ступени. Где первая ступень перегенерации находится внутри корпуса печи, а компактный пароперегреватель является отдельным конструктивным узлом, и исполняет роль второй ступени, являясь пароперегревателем. То есть дополнительным теплотехническим устройством, догревающим водяной пар до требуемых кондиций. Такое деление на отдельные конструктивные и функциональные модули позволяет обеспечить функцию компактности в целом при транспортировке банной печи. Так как габариты компактного пароперегревателя, благодаря его конструктивному устройству, могут быть подобраны так, что во время транспортировки он помещается в полость первой ступени парогенератора. Это приводит к оптимизации транспортных габаритов, при сохранении тепловой эффективности изделия «печь для бани». 2 ил.
