Description
Technical field
The utility model relates to a kind of steam boiler, and being specifically related to a kind of is the steam boiler of fuel with hydrogen.
Background technology
As everyone knows, hydrogen is a kind of explosive hazardous gas, and when aerial content reached finite concentration, one met kindling material, just will produce scintillation, blasts.The LEL of this gas is 4.1%, on be limited to 74.2%, the explosion limit scope is very wide, and is dangerous big.Simultaneously, hydrogen is again a kind of clean energy resource, especially in the chlorine industry field, in the production process of caustic soda, pays hydrogen producing, and except that part was used as raw material, a large amount of hydrogen was all by emptying.How with the fuel of hydrogen as steam boiler, making its pair producing steam, to reduce production costs, improve economic benefit of enterprises, is the very problem of concern of numerous scientific and technical personnel institute.
Utilize hydrogen to produce steam for fuel, its crucial equipment is steam boiler, and conventional boiler and general gas fired-boiler be not owing to consider the particularity of hydrogen, therefore can not be used for the burning of hydrogen, for this reason, design a kind of combustion hydrogen steam boiler, be relevant branch of industry very expectation.
Summary of the invention
The utility model technical issues that need to address are a kind of combustion hydrogen steam boilers of design, to satisfy the needs of relevant department.
The technical solution of the utility model: a kind of combustion hydrogen steam boiler comprises housing, is provided with combustion chamber, convection cell, flowering baffle, heat exchange fire tube, heat exchanging water pipe, water distributor, down-flow pipe and the combustion of hydrogen member of refractory liner.
Said housing is vertical tower body, and its top is connected with chimney, and convection cell is arranged on tower body top, and the combustion chamber is arranged on the tower body bottom, and flowering baffle is arranged on the top and the bottom of convection cell;
The heat exchanging water pipe is arranged in the combustion chamber, the one end passes and exceeds flowering baffle and is connected with convection cell, the water distributor of the other end by being arranged on combustion chamber below is connected with down-flow pipe in being arranged on refractory liner, and the other end of down-flow pipe is connected with convection cell by flowering baffle;
The heat exchange fire tube is arranged in the convection cell, is fixed on the flowering baffle and with combustion chamber and chimney to be connected, and steam (vapor) outlet is arranged on the top of convection cell, and water inlet is arranged on the bottom of convection cell;
The combustion of hydrogen member is arranged in the combustion chamber of housing bottom.
Said combustion of hydrogen member comprises burning to be chewed, and can preferably adopt the outer multifuel combustion of diffusion type to chew, and produces tempering phenomenon, damage equipment when avoiding burning.The outer multifuel combustion of said diffusion type is chewed and is meant that combustion gas and air divide two-way to enter the combustion chamber, and mix on the limit, the limit burning, and combustion gas does not contact with air before burning.
Further, be provided with explosion proof door on convection cell top and bottom, combustion chamber.
Because down-flow pipe is arranged in the refractory liner, be not heated, and the heat exchanging water pipe is subjected to the flame radiation heating in the combustion chamber, water temperature rises, water upwards flows in the heat exchanging water pipe, therefore, water in the convection cell is entered by down-flow pipe enter the heat exchanging water pipe after water distributor distributes, and then enter convection cell.
Combustion hydrogen steam boiler of the present utility model, adopt vertical, no dead angle in the burner hearth, convection part adopts the one way heat exchange, flow of flue gas is unobstructed, and flow resistance is little, can avoid unburned hydrogen to gather, produce blast, adopt the outer multifuel combustion of diffusion type to chew, can effectively prevent tempering, and be provided with explosion proof door on convection cell top and bottom, combustion chamber, explosion-proof area is big, and is safe and reliable.
