Abstract:
본 발명은 연소부피를 줄이는 매트릭스(8)를 갖춘 증기발생 보일러에 관한 것으로, 이 매트릭스(8)는 증기발생 보일러의 연소로(5) 내에서 바람직하기로 연료흐름 및 산화제흐름(12,11)의 하류에 놓여서, 매트릭스수단이 종래 보일러보다 짧은 연소구획부를 생성하여 증기발생 보일러의 부피를 줄일 수 있게 한다.
Abstract:
PROBLEM TO BE SOLVED: To provide a boiler capable of materializing low O 2 , low NOx, and Low CO. SOLUTION: This boiler 1 is equipped with a premixed gas burner 10 and water pipes 21, 22, 23 disposed in close vicinity of the premixed gas burner 10. Premixed gas is jetted out from the premixed gas burner 10 while making an prescribed angle to the water pipes 21, 22, 23, and a fuel supply part 50 capable of supplying either one of fuel gas or the premixed gas is provided at a location separated from the premixed gas burner 10 toward its downstream side by a prescribed interval.

Abstract:
The present invention relates to a hybrid combustion system (1) wherein rich homogeneous combustion and lean catalytic combustion are carried out consecutively, which results in zero NO x emission and is used for obtaining domestic hot water. The present invention relates to a combustion system wherein two serially connected heat exchangers units, which are located in the outlets of the rich homogeneous combustion unit and the lean catalytic combustion unit, transfers the heat generated during combustion reactions into domestic radiator heating water and/or tap water for hot water generation.
Abstract:
A method for producing steam while concurrently reducing emissions. The method includes combusting fuel and an oxidant stream having a high concentration of oxygen in a combustion zone having multiple combustion chambers and heat exchangers to produce a flue gas. The flue gas is subsequently cleaned in a dry flue gas cleaning chamber by contacting it with a dry adsorbent. In one embodiment, the method advantageously regenerates the dry adsorbent so that the dry adsorbent can be subsequently recycled back into the dry gas flue chamber.
Abstract:
Dispositif d'échauffement d'un fluide utilisable notamment dans un lanceur de fusée pour pressuriser un ergol liquéfié. Selon l'invention, ce dispositif comprend un premier brûleur (21) réalisant une première combustion entre un ergol limitant (L1) et un ergol en excès (E), et une première unité d'échangeur (10, 31) dans lequel des premiers gaz brûlés (B1) issus de ladite première combustion cèdent de la chaleur au fluide (F); il comprend en outre au moins un deuxième brûleur (22) dans lequel on injecte les premiers gaz brûlés (B1) d'une part et de l'ergol limitant (L2) d'autre part pour réaliser une deuxième combustion entre l'ergol limitant (L2) et au moins une partie de l'ergol en excès imbrûlé présent dans les premiers gaz brûlés (B1); les deuxièmes gaz brûlés (B2) issus de ladite deuxième combustion circulent dans une deuxième unité d'échangeur (10, 32) pour céder de la chaleur au fluide (F); les gaz brûlés (B1, B2) issus de chacune des combustions circulent dans des tubes pour gaz brûlés (31, 32) au sein d'un même échangeur global (10) composé desdites unités d'échangeur (10, 31, 32) dans lequel ils cèdent de la chaleur au fluide (F), ce dernier circulant entre les tubes pour gaz brûlés (31, 32).
Abstract:
An oxy/coal combustion system (102) and method include a furnace (104) arranged and disposed to receive and combust a first solid fuel (110) to form a combustion fluid(118), a convective section(106) having one or more inlet devices, the convective section arranged and disposed to receive and combust a second fuel (105) in the presence of the oxygen, and one or more heat exchangers (120) arranged and disposed to exchange heat with the combustion fluid (121).
