45 ton Corner Tube Biomass Steam Boiler in Costa Rica


A set of 45 ton rice husk biomass fired corner tube chain grate boiler manufactured by was sold to Costa Rica. Our sales manager Mr. Gao also stayed in the local for one month in boiler install. This is our DHL corner tube boiler, vertical structure, single drums. Our sales manager and boiler engineer on this project had been Costa Rica over one month in boiler install site. This boiler burns biomass fuel and coal fuel.

Corner tube boilers were developed for steam output. The design was based around two factors that, along with excellent water circulation, should be appropriate cooling even at light loads. The unheated downcomers form the supporting frame work and not the thermally loaded tubes, hence the name corner tube boiler. Moreover, the piping-arrangement system is also responsible; to manage the riser tubes and water distribution in riser tubes and down comers and to collect the steam water mixture and to make a certain amount of pre-separation of steam and water mixture.
In corner tube boiler, the water circulation takes place simultaneously through the drum and through the unheated down comers outside the drum. The water flows down from the drum through the down comers and it is distributed in the different riser tubes. The steam-water mixture circulates and flows in the upward direction through the riser tubes.

In the radiation heated area through the pre-separator (also known as cross-collector), occurs the pre-separation of steam from the steam water mixture. The separated steam flows through the overhead pipe and the steam-water mixture flows through the collector pipe to the drum as well. In the drum occurs the final separation of steam from steam water mixture. The rest amount of water flows through the unheated return tubes and downcomers to the rear wall distributor/header. Due to the water returning from the unheated downcomers a lively circulation takes place.
