A fireplace construction made of solid masonry units having a rear wall with a symmetrical bulge formed by a lower angled portion, a central vertical portion, an upper angled portion, and an upper vertical portion. Each portion is slightly spaced apart from the adjacent portion to provide a space for air to flow into the firebox. One or more air ducts route air from the room to the space between both the lower vertical portion and the lower angled portion and the space between the lower angled portion and the central vertical portion.

A small stove assorted with smokeless combustion of combustible solids/semisolids, a stove core and a shape of briquette are to ensure that a cylindrical briquette stack is quickly ignited in a smokeless state. A section A stove core inner ring and a flame concentrator are made of a selected high-whiteness aluminum silicate fiber with superior thermal insulation/resistance effects, and are processed for, e.g., blocking the micropores inner circumferential surface, and a stove core outer ring is made of cheaper foam glass, foam ceramic or calcium silicate modules. An underlying briquette with a concave top is designed to enable an easy, convenient and fast alignment of vent holes. The overall cross-sectional area of the vent holes is expanded by 30%-50% as compared with the area of the anthracite briquettes with the same diameter, and the inner ring vent holes are mainly expanded.

A fireplace construction has: a) a solid floor; b) side walls extending upward from the floor to a flue; c) a rear wall having: i) a lower vertical portion, ii) a lower angled portion extending forward into the firebox and spaced slightly apart from the lower vertical portion to provide a space for air to flow into the firebox between the lower vertical portion and the lower angled portion, iii) a central vertical portion positioned forward of the plane of the lower vertical portion and spaced slightly apart from the lower angled portion to provide a space for air to flow into the firebox between the lower angled portion and the central vertical portion, iv) an upper angled portion extending rearward from the plane of the central vertical portion, and spaced slightly apart from the central vertical portion to provide a space for air to flow into the firebox between the central vertical portion and upper angled portion, and v) an upper vertical portion positioned rearward of the plane of the central vertical portion, and optionally spaced slightly apart from the upper central angled portion to optionally provide a space for air to flow into the firebox between the upper vertical portion and upper angled portion, wherein the lower central angled portion, the central vertical portion, and the upper central angled portion combine to form a smooth, symmetrical bulge in the back wall extending into the firebox; d) one or more air ducts effective to route air from the room to the space between the lower vertical portion and the lower angled portion, and from the room to the space between the lower angled portion and the central vertical portion; d) an open front; and e) an open top effective for directing air and combustion gasses from the firebox to a flue.

The lower angled portion may comprise a first lower angled portion and a second lower angled portion spaced slightly apart from the first lower angled portion to provide a space for air to flow into the firebox between the first lower angled portion and the second lower angled portion. In this embodiment the central vertical portion may comprise a first central vertical portion and a second central vertical portion spaced slightly apart from the first central vertical portion to provide a space for air to flow into the firebox between the first central vertical portion and the second central vertical portion, and wherein the fireplace construction includes one or more air ducts effective to route air from the room to the space between the first lower angled portion and the second lower angled portion. Further, the fireplace construction preferably includes one or more air ducts effective to route air fro

A hearth pad for live ember protecting a floor. The hearth pad comprises a backing for being placed onto the floor. The backing is made of a flexible sheet material. A plurality of tiles is disposed on the backing and adhered thereto using a flexible adhesive. The tiles are made of a rigid material. A flexible filler is disposed in gaps between adjacent tiles.
