Steam production apparatuses are provided. The apparatuses can include at least two compartments that are mechanically engaged. Processes for the production of steam are also provided. The processes can include providing liquid water to a reactive material within a first compartment to generate steam within the first compartment; transferring at least some of the steam to a second compartment that is mechanically engaged with the first compartment; and exposing the steam from the first compartment to material within the second compartment that extends when exposed to the steam, the extending of the material reducing the volume of the first compartment.

Provided is a boiler configured to perform heating by a heat generation section provided with heat generation bodies in a container and capable of properly charging a circulation path including, as part thereof, the inside of the container with required gas. A boiler includes: heat generation bodies; a container configured such that the heat generation bodies are provided inside and configured chargeable with gas with higher specific heat than that of air; and a circulation path including, as part thereof, the inside of the container, the circulation path being a path in which gas circulates. When the charging process of charging the circulation path with the gas is performed, a circulation amount and a gas concentration in the circulation path are monitored.

A method for controlling carryover in a chemical recovery boiler. The method comprises feeding black or brown liquor to a furnace of the chemical recovery boiler through an injection gun to burn the black or brown liquor. The chemical recovery boiler comprises a bullnose, which narrows the furnace, and a first superheater, of which at least a part is arranged at a higher vertical level than the bullnose. The method comprises measuring information indicative of a spatial temperature distribution on a cross section of the furnace, wherein the cross section is above the injection gun and below the first superheater; determining primary information indicative of carryover using the information indicative of the spatial temperature distribution on the cross section of the furnace; and controlling a temperature of the black or brown liquor that is fed to the furnace using the primary information. In addition, a system for performing the method.
